A lone wizard against a living microcosm. Auto-cast 25+ spells, dodge thousands of enemies, and level up into a screen-clearing storm — solo or in online co-op. Buttery-smooth and tiny, it runs great even on weak PCs and the Steam Deck.

Become an unstoppable storm of spells
Microcosm is a fast, juicy survivor-like (bullet heaven). Move, dodge, and let your auto-casting spells shred wave after wave of monsters. Each run you pick new spells and upgrades, stacking them into a screen-clearing build — then push your luck against ever-bigger hordes and periodic bosses.
