Survive while being chased by the rain in an ecosystem that does not treat the player as the main character. The cause of most failures is ``proceeding without being explained how karma and gates work,'' so let's resolve that first.

ABOUT

What is Rain World?

A survival platformer where you play a Slugcat traveling through vast rain-soaked ruins. The world has 12 regions and at least 1,600 rooms, with an ecosystem that does not make the player its central figure. Predators fight each other, prey flee, and you are neither strongest nor weakest. Periodic devastating rain imposes a time limit: gather food and enter a shelter before it arrives. Limited explanations cause many players to give up, but that uncompromising design also inspires enthusiastic fans. Released in 2017, with over 56,000 Steam reviews and a Very Positive rating in the source. Japanese is supported.

「A book whose unexplained design led to failures and enthusiastic fans at the same time.」 — From Steam store results

🌀 Six core mechanisms

cycle and rain

A catastrophic downpour arrives every cycle. You die if you fail to enter a shelter before the rain begins. Exploration time is therefore limited each cycle, making time management central to the game.

food meter

Eating wild plants and small animals fills the food meter. Entering a shelter with the required amount saves the game. Food eaten beyond the requirement carries over to the next cycle.

karma

Karma increases by 1 each time you enter a shelter with the required amount of food. It goes down when you die. Karma is not just a score, it is the key to passing through the gates described below.

karma gate

To move between regions, you need to pass through a karma gate, and you can only pass through it if your current karma is greater than or equal to the gate's required value. The required value also serves as a guide to the difficulty level of the area ahead. Once a gate has been passed through, it will not open again during that cycle.

karma flower

Flowers that bloom in specific locations. When you eat, your karma is reinforced, and the next time you die, instead of losing your karma, the reinforcement is consumed. This is insurance in situations where you want to preserve your karma.

ecosystem

Players are not the main characters in the food chain. Predators fight each other, and prey flees. Rather than fighting head-on, there are many situations where it's more effective to hit creatures against each other or to take advantage of gaps to sneak past.

💡 Things beginners should know

The true meaning of “difficult” is the lack of explanation.

This work doesn't really explain how it works. If you proceed without knowing the relationship between karma and gates, you will suddenly run into an impenetrable wall and feel unreasonable. On the other hand, once you understand how it works, the perceived difficulty level goes down significantly.

I'll definitely be back before the rain comes

The biggest cause of death is getting caught in the rain while exploring. If you decide at the beginning of the cycle how far you should go before turning back, the number of unnecessary deaths will be drastically reduced.

Find a way to avoid fighting

Fighting head-on with a predator is basically at a disadvantage. Throwing things to distract them, colliding with other creatures, waiting for an opening to pass through - you'll survive better if you focus on evasion.

Can be adjusted in remix settings

This game has various customization settings for Remix, allowing you to change the difficulty level and accessibility to your liking. If you don't care about the pure experience, you can use it.

FAQ

Rain World FAQ

Q1 What kind of game is Rain World? ▼
A

This is a survival platformer where you become a ``slug cat'' and travel through ruins submerged in the rain. The world, which consists of 12 regions and at least 1,600 rooms, has an ecosystem that does not treat the player as the protagonist. The time limit is set by periodic catastrophic heavy rains, and you need to secure food and go to shelter before that time limit. Developed by Videocult, published by Akupara Games, Released on March 28, 2017. Available in Japanese.

Q2 How does Karma and Karma Gate work? ▼
A

Karma increases by 1 when you enter the shelter with the required amount of food, and decreases when you die. To move between regions, you must pass through a karma gate, and you cannot pass through it unless your current karma is greater than or equal to the gate's required value. The required value also serves as a guide to the level of difficulty ahead. Note that once a gate has been passed through, it will not open again during that cycle.

Q3 What is "Karma Flower" for? ▼
A

A flower that grows in a specific location. Eating it will strengthen your karma. The next time you die, your reinforcement will be consumed instead of your karma going down, so it's an insurance policy for situations where you want to maintain your karma. This is effective when you want to maintain the state in which the gate's required value has been reached.

Q4 Why is it said to be so difficult? ▼
A

Because it barely explains how it works. If you proceed without knowing the relationship between karma and gates, you will suddenly hit an impassable wall and feel unreasonable. In addition, players are not the main players in the food chain, and there is basically no way to win if you fight a predator head-on. If you switch to the policy of Understanding the mechanism and getting through without fighting, the perceived difficulty will be greatly reduced.

Q5 If it is too difficult, can it be adjusted? ▼
A

Yes you can. This game has a Remix customization setting that allows you to change the accessibility and difficulty level to suit your preferences. There are also tutorial messages added later to help you understand the ecosystem. If you don't care about pure initial experience, there is no problem in using it.

Q6 What games are similar? ▼
A

Works with walkthroughs on this site include ANIMAL WELL, which involves exploration and puzzle solving with little explanation, COCOON, which deciphers a quiet world, and Stoneshard, whose main theme is survival itself. If you like the feeling of being left unexplained to the world, Caves of Qud will suit you.
