Purgatory is a two player, split screen game, developed over one weekend as part of the IGDA Global Game Jam. In two overlapping parallel universes life and death fight for supremacy. Defeat may only be assured by sending the enemy to purgatory and finishing them once and for all.
The realms of life and death are not the same - your shots are restricted by your own realm. Upon death you are forced into purgatory - find the portal to escape, or if your enemy has succumbed, hunt and defeat them!
