Case in point, Rain World [official site], a 2D game with wonderful sci-horror environments, sinister shadow-beasts and the hypnotic leap’n’crawl of the ‘slugcat’ it stars.
Rain World’s due out on Steam for $20 on March 28th, developed by Videocult and published by Adult Swim.
This is intriguing too: “Both prey and predator, the creatures in Rain World’s living ecosystem follow their own survival instincts, learning from each encounter.”
The titular and “bone-crushing” rain presents its own threat in addition to the creepy-crawlies and nightmare-stags.
