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.

Features

Bosses & escalating waves that fire their own deadly volleys.
