Rain World

Rain World is an action-platformer for the Nintendo Switch eShop developed by Videocult.

Gameplay
The player is given little explicit guidance and is free to explore the world in any direction via pipes and passages that pass through 1600 rooms, each with randomized enemies, and 12 different regions.

Enemies possess dynamic AI and exist in the game's world perpetually, then you'll need to evade the predators that adapt to catch you.

Plot
You control the part-slug and part-cat Slugcat. The world around is full of danger and you're alone in a hostile, ruined, and obtuse 2D world in search of the family from whom you was separated.
