Versus Purgatory

Two spirits, an angel and a devil, were sentenced to Purgatory for their deviancy. Despite their hatred for one another, they must work together to shoot, blast, and zap their way out of the ever-changing labyrinth they've been trapped in.

Versus Purgatory is a micro-roguelike shoot-em-up with mind-bending gameplay inwhich you delve into a dungeon, controlling two characters at the same time.
