Rain World Wiki
Rain World was initially proposed for release late-2014, early-2015, but the Developers have amended that by saying it's "still too soon to tell on an ETA. But our goal is to make the game as awesome as possible, so we will do whatever that takes."
Rain World is a 16-bit survival platformer set in an abandoned industrial environment scourged by a shattered ecosystem. Bone-crushing intense rain pounds the surface regularly, making life as we know it almost impossible. The creatures in this world hibernate most of the time, but in the few brief dry periods they go out searching for food.
You are a lonely, nomadic slugcat, both predator and prey in this land. You must hunt enough food to survive another cycle of hibernation. Other, bigger creatures have the same plan.
Inspired by the aesthetics and simplicity of 16-bit classics, the gameplay consists of platforming and fast-paced sneaking; both sneaking on your prey and sneaking in order to avoid larger creatures. A large focus of the development has been on enemy AI: they are cunning, vicious and they are always hunting you.
Rain World is currently in development for PC, Mac, Linux and PS Vita, and can be found on Steam Greenlight.
