If you don't kill a lost soul or a dark spirit in 120 seconds they might heal (Or break the game) Arrow keys to move Mappy, WASD to move Mappo. (I took the walking thing from Earlobe7, that's all I took) C or X to interact. (You don't need it though) Z to sprint. Press buttons to activate. Wind does 10-30 damage at random. Smack does 20 damage. rustle does... nothing.
Changes for V2: Enemies don't get one last attack. Bugs: Ghost is a bit glitchy.
