This fast paced action title is the gold standard of the "Rogue-lite" genre, famously blending the exploration of a traditional 2D side scroller with the punishing, permadeath structure of a modern dungeon crawler. You control a mass of sentient cells that inhabits a headless corpse, reanimating it to fight through a sprawling, ever changing island fortress. The gameplay is built around a "fail, learn, and grow" loop, where every death provides you with permanent upgrades that make your next run slightly easier. It is widely praised for its incredibly fluid movement and a combat system that feels weightless yet impactful.
