⚠️ Major spoiler warning: read before proceeding

This walkthrough discusses the story, revelations and optional discoveries through the ending. Discovering the connections in the disrupted timeline is central to the first-play experience. If you want to preserve those revelations, finish once before reading. During play, use a specific sticking-point section carefully; on another run, plan cards and achievements by scene.

🚨 Spoilers include

  • The crash’s cause(Jimmy deliberately causes the collision)
  • The violence in Anya’s past(content note: sexual assault)
  • Daisuke’s fatal injuries(the vent incident and its consequences)
  • What Curly learns before the crash(his failure to protect Anya and later silence)
  • Interpretations of surreal scenes(Polle, cake and birthday imagery)
  • Possible meanings of the title(rinsing as a metaphor for erasing words, memory or responsibility)
  • Ending(the birthday table, Curly’s cryopod and Jimmy’s suicide)

💡 Disturbing themes

Although the game is short,Curly’s injuries, Daisuke’s death and the violence against Anya can be distressing. The intensity is personal; no particular duration of emotional effects is predicted here. Consider a setting, time and pace that suit you. Consult the Steam mature-content notice for sexual violence, self-harm and bodily injury before deciding whether to play.

Detailed section 2 — major spoilers
📖 Story topic1: Before the crash

📅 Topic overview

Position in time: Before the crash

Main location: Aboard the Tulpar

Central event: During the voyage, the crew learn that Pony Express is closing. Anya discloses her pregnancy following Jimmy’s assault. The exact date of the assault and a pre-departure Earth scene are not established here.

Revelation: Jimmy’s harm predates the crash. Anya tells Curly about her pregnancy and fears; he fails to protect her adequately.

🎯 Opening and crash-reference notes

  • Pay attention to the opening imagery: Observe the controls, alarms and viewpoint. Exact visual details should be checked against the scene rather than inferred from this overview.
  • The opening and Jimmy’s viewpoint: Curly’s injuries and Jimmy’s account establish an incomplete picture of the disaster. This is a topic grouping, not a verified numbered gameplay chapter.
  • Damaged cryopods: Escape options are limited, but one pod remains working and becomes important later. The earlier statement that every cryopod is disabled was incorrect.
  • Anya’s employee card: Left interior wall of the cockpit locker in the opening emergency-key scene, community chapter 1. Collect it during that scene for Anya’s achievement.
  • Progressing beyond the scene: Follow the current objective. An exact chapter-ending command announcement has not been verified here; the story remains linear.
Detailed section 2 — major spoilers
📖 Story topic2: The deliberate crash

📅 Topic overview

Position in time: The collision

Main location: Tulpar Cockpit

Central event: Jimmy disables the autopilot and deliberately sets the collision in motion, gravely injuring Curly.

Revelation: The apparent accident is revealed as deliberate. Curly is a victim of the crash, while his earlier failure to protect Anya remains relevant.

🎯 Survival-reference notes

  • Lounge conversations: Shared-space conversations establish Anya’s discomfort, Daisuke’s optimism and Swansea’s cynicism. Their placement is not asserted as one verified all-crew ration scene.
  • Caring for Curly: Medical scenes show Anya’s care and discomfort around Jimmy. Specific gestures should be distinguished from interpretation.
  • Inspecting the cargo: Finding mouthwash instead of useful supplies connects the crisis to the title and the company’s priorities.
  • Exploration details: Inspect available Lounge and ship objects. Individually visitable crew bedrooms and hidden diaries are unverified; employee cards have five specific scene locations.
  • Jimmy’s inner account: Compare his explanations with what other characters say. An exact chapter-ending monologue has not been established here.
Detailed section 2 — major spoilers
📖 Story topic3: Drifting and survival

📅 Topic overview

Position in time: Early after the crash

Main location: Lounge / Cargo

Central event: Jimmy takes command. The crew later discover that the shipment contains only mouthwash; supplies and the prospect of rescue are bleak.

Revelation: The cargo revelation supports a reading of workers treated as disposable and connects with the title’s irony.

🎯 Daisuke and the damaged vent

  • Jimmy sends Daisuke through the vent: This is internal access through a damaged vent, not an external spacewalk. Question how Jimmy uses the intern’s trust and authority.
  • Anya’s absence at this point: She has already locked herself in Medical and dies before Daisuke’s death; an objection scene at the vent is not established.
  • The fatal injury: Daisuke is gravely injured entering through the damaged vent. The event is fixed, without a rescue branch that prevents it.
  • Utility and the vent context: Swansea guards access to Utility, where the cryopods and damaged vent matter. A separate searchable Engine Room and Daisuke preparation items are unverified.
  • The axe: A player guide gives 2609 for the axe used to free Daisuke from foam. This is separate from the later fatal vent injuries and does not prevent his death. Actual inputs on the current version have not been tested here.
  • Progressing beyond the scene: The injuries destroy the remaining trust. An exact fade-out into a subsequent hallucination chapter is unverified here.
Detailed section 2 — major spoilers
📖 Story topic4: Daisuke’s death

📅 Topic overview

Position in time: Later after the crash

Main location: Utility / damaged vent / Medical

Central event: Jimmy sends Daisuke through the damaged vent. The injuries are fatal, and Swansea ends his suffering with the axe.

Revelation: Jimmy’s vent decision exposes his abuse of Daisuke’s trust and the collapse of protective authority.

🎯 Surreal-sequence notes

  • A central part of the presentation: Jimmy’s distorted perspective brings together Polle, cake and birthday imagery; symbolic meanings remain interpretive.
  • Polle, the horse mascot: A threatening version appears in the warehouse sequence among mouthwash crates. Reading it as denial or guilt is analysis, not an official definition.
  • Cake and birthday imagery: The contrast between celebration and violence can be read as denial. Related imagery returns in the final scenes.
  • Distorted subjective spaces: Faces and environments distort within Jimmy’s perspective. A reading about fractured identity is possible; an exact repeated “Who am I?” line is not verified here.
  • Questioning the narrator: Compare the surreal account with established events. No measured claim about what most players conclude at this point is made.
Detailed section 2 — major spoilers
📖 Story topic5: The mocktail and Swansea

📅 Topic overview

Position in time: Later after the crash

Main location: Lounge

Central event: Jimmy and Daisuke drug Swansea to gain Utility access before the vent incident. A player recipe guide lists mouthwash plus isopropyl, then the resulting drink base plus sweetener, for that spiked mocktail. The birthday mocktail is separate: water plus tonic, then its base plus sweetener. Swansea later wakes and ends the fatally injured Daisuke’s suffering; Jimmy shoots him in a later confrontation. These recipes are source-checked game interactions, not inputs tested here.

Revelation: Jimmy’s violence eventually reaches Swansea. A reading of Swansea as conscience is interpretive rather than an official explanation of the killing.

🎯 Pre-crash revelation notes

  • Pre-crash scenes: Flashbacks provide context for Jimmy’s behavior. A port stop exactly three months before the crash is not established by the sources checked here.
  • What happened to Anya: This is among the story’s most distressing subjects,involving dialogue and implications of sexual assault, rather than a directly depicted assault scene.
  • What Curly knows: Anya discloses her pregnancy and fears. His response raises questions about what a captain should do to protect a crew member, and what he fails to do.
  • Reading Jimmy’s motives: Fear of accountability is one interpretation of his deliberate crash. The precise balance of motives is not an official diagnosis or explanation.
  • The weight of Curly’s pre-crash viewpoint: Earlier interactions contrast with the post-crash situation. Not every pre-crash scene is happy; these scenes also reveal harm already present.
  • Pace the experience to suit you: Pause if needed after distressing scenes; there is no requirement to continue in one session.
Detailed section 2 — major spoilers
📖 Story topic6: Anya’s death

📅 Topic overview

Position in time: Later after the crash

Main location: Medical

Central event: Anya locks herself in Medical and dies by overdose before Daisuke dies.

Revelation: Her death confronts the player with harm Jimmy cannot erase through denial.

🎯 Reconsidering the crash

  • Curly’s viewpoint adds context to the crash: Different scenes change the initial account; an exact one-to-one replay of every opening action is not established here.
  • Jimmy deliberately causes the crash: The controls and surrounding revelations establish his deliberate action; this is stronger than merely a possible fan interpretation.
  • Curly before the injuries: His response around the collision and his later enforced silence can be compared without claiming access to every private thought.
  • Reconsider the initial account: Another viewpoint overturns the apparent accident. A further run can reveal details missed initially.
  • Progressing beyond the scene: Continue through the remaining story objectives. The earlier assertion that no save points exist after this scene is unverified.
Detailed section 2 — major spoilers
📖 Story topic7: Hallucinations and the ending

📅 Topic overview

Position in time: Final scenes

Main location: Surreal scenes / Lounge / Utility

Central event: Jimmy’s surreal experiences intensify. He arranges the bodies at a birthday table, places Curly in the working cryopod, claims to have fixed things and dies by suicide off-screen. The final viewpoint is Curly’s as the pod activates.

Revelation: The crash, violence and denial can be connected through a reading of the title as attempted cleansing; this is interpretation.

🎯 Surreal scenes and the ending

  • One fixed outcome, without branches: Jimmy arranges the bodies at a birthday table with Curly. The player cannot choose an alternative story ending.
  • Birthday and cake imagery: The imagery can be read as distorted celebration and failed denial. This remains interpretation rather than an official symbolic key.
  • Possible meaning of “Mouthwashing”: Reading the title as Jimmy trying to wash away wrongdoing is one interpretation; no measured claim that it is the most supported reading is made.
  • Connecting violence, the crash and denial: The final scenes invite the player to reconsider earlier events as a witness. Not every symbolic detail has one confirmed answer.
  • The final cryopod and suicide: Jimmy puts Curly into the working cryopod, claims to have fixed things and dies by suicide off-screen. The final perspective is Curly’s; Go Home is associated with finishing the game.
  • After finishing: Responses differ. If helpful, compare interpretations with videos or player discussions, while respecting your own pace; no particular duration of distress is predicted.
Detailed section 3 — major spoilers
🏆 All 18 achievements and The Good Ending

Mouthwashing’s Steam achievement list has 18 achievements. Some follow required actions, while others are optional. Deliberate cleanup includes five employee cards and several scene-specific interactions.

🎯 Planning achievement cleanup

  1. Focus on the story first: Experience the ending and clues first, without forcing every collectible into the first run.
  2. Five employee cards: Curly, Jimmy, Anya, Daisuke and Swansea: Each unlocks the achievement named for its crew member. See the five-card guide below.
  3. The Good Ending achievement: Be killed by Swansea ten times in the graveyard. This Steam achievement does not create another ending.
  4. The Yimpy secret: Maintain eye contact with Yimpy for ten seconds. Two player references identify the Medical corkboard; exact chapter numbering and any zoom requirement remain uncertain.
  5. 「The Name Of The Game」: Use a bottle of Mouthwash, as stated by Steam; an exact inventory rejection prompt is unverified here.
  6. 「Wasteful」: Mix Pony Express’s special mocktail for Curly’s birthday party. The earlier cake-order requirement is unsupported.
  7. 「Sock Puppet」: Sock Puppet requires repeatedly opening and closing Curly’s mouth, as stated by Steam.

📊 Achievement notes

  • Total: 18 achievements
  • Story-related entries: Some accompany required story actions; not every achievement is automatic.
  • Do not confuse The Good Ending with an ending: An optional achievement, not a separate ending.
  • Missable scenes: Cards and interactions can belong to specific scenes; collect the cards in their listed scenes.
  • Repeat playthrough: Plan missing cards and optional achievements on a further playthrough.
Detailed section 4 — major spoilers
🪪 All five employee cards

The principal collectible set is five Employee Cards. Each unlocks its crew-named achievement: Curly, Jimmy, Anya, Daisuke or Swansea. No separate photograph set is verified. Collect cards in their listed scenes; unrestricted chapter replay is not tested here.

🪪 Anya’s employee card Cockpit / locker

Location: Left interior wall of the cockpit locker

💡 Tip: Opening emergency-key scene, community chapter 1. Collect it then for the Anya achievement.

🪪 Swansea’s employee card Lounge / vending machine

Location: Broken Lounge vending machine’s lower dispensing tray during the axe search

💡 Tip: Inspect the tray in community chapter 8 for the Swansea achievement.

🪪 Daisuke’s employee card Lounge / shared space

Location: Beside the board game on the coffee table in front of the sofa

💡 Tip: Community chapter 9, “Check On Curly.” Collect the card before checking on Curly for the Daisuke achievement.

🪪 Jimmy’s employee card Lounge / Polle statue

Location: Inside the hat beside the broken Polle statue in the Lounge

💡 Tip: Inspect the hat during the community chapter 16 cocktail scene for the Jimmy achievement.

🪪 Curly’s employee card Utility / working cryopod

Location: Utility floor beside the right-hand cryopod, community chapter 19

💡 Tip: Collect it before taking the gun for the Curly achievement; it is not in a private crew cabin.

🔁 Further playthroughs and cleanup

The story remains linear. Knowing the revelations lets you notice different details on a further run. Alongside achievement cleanup, revisiting the following topics can offer new connections, like watching a film again.

🎬 Compare viewpoints before and after the crash

Pre-crash Curly scenes and post-crash Jimmy scenes change one another’s meaning. After learning the truth, revisit how Jimmy presents events.

🎬 Follow Polle’s symbolic role

Pony Express’s horse mascot becomes a threatening figure in later surreal scenes. Reading it in relation to Jimmy’s guilt is one interpretation; compare repeated details after finishing.

🎬 Collect the five employee cards

Each card unlocks a crew-named achievement. Plan the five scene-specific locations rather than searching a persistent set of rooms after the ending.

🎬 The Good Ending achievement

Steam specifies being killed by Swansea ten times in the graveyard. This is not a separate ending, and the unlock has not been tested in-game here.

🎬 The Yimpy secret

Maintain eye contact with Yimpy for ten seconds. Two independent player guides identify the Medical corkboard drawing; exact chapter numbering and whether zooming is required remain uncertain.

🎭 Details to reconsider

  • Anya’s dialogue and behavior: Reconsider her fears and constraints after learning the context. Do not assume a first impression that blames her or invent a fixed chapter-2 sequence.
  • Jimmy’s decision about the vent: Knowing the consequences changes how an apparently useful order can be read as exploitation and self-preservation.
  • Cake imagery in surreal scenes: Compare earlier images with the final birthday table; symbolic connections remain interpretive.
  • Curly’s silence: Compare his enforced inability to speak after the crash with his earlier response to Anya.
  • Swansea’s sarcasm: His words gain context from his working life and bond with Daisuke. The claim that he already knows everything is not established.

⏱️ The roughly 2–3-hour story: playtime estimates

The short narrative often takes around 2–3 hours for a first run. The following source estimates are editorial and untested, not measured chapter durations or a guaranteed completion schedule.

📅 First playthrough

  • Pre-crash/opening topic: source estimate 15 minutes, unmeasured.
  • Survival/cargo topic: source estimate 25 minutes, unmeasured.
  • Daisuke topic: source estimate 30 minutes, unmeasured.
  • Surreal-scenes topic: source estimate 30 minutes, unmeasured.
  • Pre-crash Curly topic: source estimate 20 minutes, unmeasured.
  • Crash-revelation topic: source estimate 15 minutes, unmeasured.
  • Final-scenes topic: source estimate 30 minutes, unmeasured.
  • First-run estimate: often around 2–3 hours. The seven source estimates above total 165 minutes, so the earlier 2–2.5-hour sum was inconsistent.

🔍 Careful exploration

  • Allow additional time as needed; the earlier 15–30 minutes per chapter was unmeasured.
  • Private crew-room diaries: not verified searchable objects.
  • Shared-space dialogue: inspect available interactions; an all-choices dialogue checklist is unverified.
  • Stockroom evidence: a separate searchable stockroom and hidden evidence set are unverified.
  • Cockpit logs: an exhaustive readable instrument-log collection is unverified.
  • Engine Room records: a separate searchable room and maintenance-record collection are unverified.
  • Earlier exploration estimate: 3–4 hours, untested; time depends on the player.

🏆 Further run for cleanup

  • Further full-run source estimate: around two hours, untested.
  • Five employee cards: check each specific scene.
  • The Good Ending source estimate: ten additional minutes, untested.
  • Yimpy source estimate: five additional minutes, untested.
  • Action-related entries such as Wasteful: check the relevant scene.
  • Review all 18 achievement entries.
  • Earlier complete-cleanup estimate: 4–5 hours, untested and not guaranteed.

💡 Planning your time

  • First-run estimate: around two hours, varies: A concentrated session can help connect scenes; taking a break does not invalidate the experience.
  • Cleanup-run planning: the earlier 3–4-hour estimate is untested: Prioritize the five card scenes and any missing interactions rather than exhaustive searches of invented rooms.
  • Leave time between runs if useful: Reflecting on the story may help; waiting exactly one day is not a requirement.
  • Choose a comfortable setting and audio level: Headphones can help with sound cues; a dark room or late-night session is optional.
  • A concentrated alternative to a hundred-hour roguelike: Its appeal is the concentrated story. This does not guarantee one fixed playtime for every player.
Detailed section 7 — major spoilers
❓ Frequently asked questions
Q1. How long does it take to finish?
A first story playthrough often takes around two hours, or longer when exploring carefully. The earlier three-hour estimate for every achievement is untested and not a guarantee. A concentrated session may help connect scenes, but take breaks as needed.
Q2. Is there combat or difficult action?
Most play involves exploration, dialogue and puzzles rather than a full survival system. Later scenes include stealth and use of a gun. Their difficulty depends on the player; this guide does not promise that every action sequence is easy.
Q3. Are there repeat-run features or multiple endings?
The story has one fixed ending, despite its nonlinear presentation. Replay can focus on cards, missing achievements or interpreting clues. New Game Plus, unrestricted normal chapter selection and post-game free roaming have not been verified here.
Q4. Does it support Japanese?
The Steam listing includes 16 supported interface/subtitle languages, including Japanese, in the retrieved snapshot. An English voice track has not been verified here. Select Japanese through available language settings; not every environmental sign’s localization has been checked.
Q5. What kind of game is it?
A first-person psychological horror adventure by Wrong Organ, with low-polygon visuals, narrative exploration and puzzles. It released on Steam on September 26, 2024. This guide covers the PC/Steam base game.
Q6. Does it contain gore or other disturbing material?
The official mature-content notice warns of violence, blood and bodily injury, alongside disturbing psychological themes. Low-polygon presentation does not remove the intensity; consult the current store notice if that affects your decision to play.

🚧 Sticking-point reference

A reference to interactions and puzzles. These scene names and solutions may still reveal events; untested precise instructions are marked rather than presented as spoiler-free or hands-on verified.

Scene Interaction or approach
A locked door will not open early in exploration Use the code scanner and inspect the plate beside the relevant door, then enter the displayed code on its keypad. Exact button prompts, plate position and confirmation control have not been tested here; follow the current UI.
Cannot enter Cargo Read the Cargo door code with the Code Scanner. Independent player guides agree on 4517. Actual inputs on the current version have not been tested here, so also check the displayed clue in your game.
Something attacks in Cargo The warehouse sequence uses sound and visual cues. The earlier stop/walk timing and left-side bridge route have not been tested here; observe the scene and current objective rather than treating those precise moves as verified.
Cannot find the mouthwash used on Daisuke The story leads through the cargo sequence to mouthwash associated with the Polle display, then back to Daisuke. The exact route has not been tested here; the fictional use on an injury is not a valid medical procedure.
Cannot enter Medical Medical is locked during the relevant scene. Jimmy and Daisuke gain Utility access before Daisuke enters through the damaged vent. The player does not simply take a safe alternate corridor into Medical.
Stuck in the vent sequence The earlier “NO TURNING BACK NOW,” no-turning and insect-dodging instructions have not been corroborated here. Follow the scene’s current objective and avoid assuming free backtracking; Daisuke’s vent injury is a fixed story event.
Cannot free Daisuke from foam The player-guide axe code 2609 belongs to the scene where Daisuke is trapped in foam. It is separate from his later fatal injuries in the damaged vent and does not unlock a route that prevents his death. Actual inputs on the current version remain untested.
Cannot open the gun case Multiple player guides identify 739 as the code for the Pony Express Protection Kit in Medical. The clue is read with the Code Scanner at the back of the Cockpit locker. Taking Notes requires opening the kit without returning to Cockpit. The specific claim about a drawer beneath the bed and actual inputs on the current version remain unverified.
Cannot operate the feeding device The earlier knob order—top once, bottom once, right once, leave left untouched—is retained as an untested source instruction. It has not been verified against the actual puzzle UI.
📌 Missable cards and achievements

Collect cards in their specific scenes. Normal menu-based chapter replay and post-game free roaming have not been verified here.

  • Anya’s employee card — Community chapter 1, opening emergency-key scene: left interior wall of the cockpit locker. Collect it during that scene.
  • Swansea’s employee card — Community chapter 8, axe search: lower dispensing tray of the broken Lounge vending machine.
  • Daisuke’s employee card — Community chapter 9, “Check On Curly”: beside the board game on the coffee table in front of the Lounge sofa.
  • Jimmy’s employee card — Community chapter 16, cocktail scene: inside the hat beside the broken Polle statue in the Lounge.
  • The Name Of The Game achievement — Steam specifies using a bottle of Mouthwash. The chapter-16 and rejected-use prompt details are not established by that description.
  • Cheater achievement — Steam’s Cheater condition is to open Cargo before acquiring the Code Scanner. The code 4517 is corroborated by multiple independent player guides, rather than supplied by the achievement description. Actual inputs on the current version have not been tested here.
  • Wasteful achievement — Steam specifies mixing Pony Express’s special mocktail for Curly’s birthday party. A chapter-7 label and cake-order requirement are not established by the official description.
  • Yimpy achievement — Maintain eye contact with Yimpy for ten seconds. Two independent guides place the drawing on the Medical corkboard, but give different chapter numbers; chapter 4 and a mandatory zoom input are not established here.
