INDIE GAME / PLAY GUIDE

Islets: 60 upgrade locations | Island entrances, hidden rooms and challenge pickups

Covers the main story, 16 bosses, directions to 60 upgrades, six ship parts and 44 achievements; remaining gaps stated · Updated 2026-10-13

Paper locations and the effects of chosen upgrade cards are separate. Check each island's missing count, then narrow candidates through room landmarks and actions. N/I/W/E/C numbers are this guide's checking labels, not official game numbers.

Reading entrances and abilities in the tables

Footage shows travel after island connections, so matching area colors do not automatically mean the same island. Combine Sky City's island counts with shrines, return doors and distinctive mechanisms.

Each row independently records the room reached, paper position and observed actions. It is not a minimum-ability acquisition order for every location. Use it for returning after new abilities.

N01's route to the ceiling recess was checked, but its uncollected paper and card screen remain under review. N14's local paper was confirmed, while its nearest-shrine connection remains explicitly unresolved.

Island	Location count	Distinctions in this guide
Northstable	17	Three papers at the same treasure-hunt endpoint are N15–N17
Inverness	16	Also inspect branches after connection with ClockWorks
Wolfpine	15	Distinguish Rainy Plains from Forgotten Rots
Eastwright	10	Distinguish Hanging Gardens from The Pits
Cinder	2	Later spiked-orb section and gray shaft

Northstable: 17 locations

Check paper height and the side used to enter each room, not merely the map dot. Defeating challenge enemies or hitting only some light orbs does not count as collecting the reward.

Five-gravestone Slam order

A challenge using five small aligned gravestones. Distinguish it from Scavenger Hunt's first large grave and visiting Forgotten Grave's spirit.

Count 1, 2, 3, 4, 5 from the left and Slam the gravestones in order 3→5→1→2→4. Check intermediate lights. If all go out, restart from 3 rather than continuing only with the last number.

Normal sword swings or arrows alone do not count as activating it. After success, collect the paper and confirm the card choice too.

Do not overlook three papers at the treasure-hunt endpoint

The dead end right of the Double Jump statue, east of the first Grave Crawler room, has three papers. Do not stop after the lower one; inspect the upper-right and upper-left recesses too.

See Scavenger Hunt for the letter order leading here. This is not a guarantee of access in every version by visiting the endpoint immediately.

Coverage and unconfirmed details

Added rooms, landmarks and checked routes for 60 upgrades. N01 has footage reaching the ceiling recess; the uncollected paper and choice screen remain under review. N14's paper and choice screen were confirmed, but its nearest-shrine connection remains unresolved. Minimum abilities for all 60, access before all connections, the remaining four paid Gates and every card value remain incomplete.
The original source checked map surroundings, on-site landmarks, pickup scenes for six Gear and the Motor through PC gameplay. Minimum abilities for all six and access before every connection remain untested.
Wall Climb's shrine and acquisition were checked in public PC gameplay by the source. A detailed coordinate-based island route and the shortest order for all abilities remain incomplete.
English and Spanish sources differ on Snoot's earliest trigger and Boss Rush unlock descriptions. The guide checks letters, the ending, 60 upgrades and Final Gate.
Japanese proper names, control keys, current-version hands-on inputs across every platform and every boss frame remain unverified.
Demajen's map was not imported because of its usage terms. An unobtained map is not counted as fully read or as having zero 25-character matches.

FAQ

Frequently asked questions (FAQ)

Q1 Hitting gravestones with the sword gives no upgrade. ▼

Use Slam on the five small aligned gravestones. Activate them in order 3→5→1→2→4 counted from the left. This is a different challenge from the large treasure-hunt grave.

Q2 Is there only one upgrade at the treasure-hunt endpoint? ▼

There are three in the same room. Inspect the lower-right and both upper recesses separately. Advance the letter quest and enter right of the statue.

Q3 Should I collect everything in this order from the start? ▼

The numbers are not the shortest progression order. This is a location index including pickups after connections and with added abilities. Choose according to missing islands and current abilities; do not declare an untested minimum ability necessary or unnecessary.
