Ultidark

Ultidark is a game about Whitey, a famous stickman athlete trapped in a dimension made to contain the evil that destroyed the world. As the spell holding the dimension weakens, stickmen begin to disappear. You must find a way out or try to lock the dimension forever while monsters haunt you and you risk becoming one yourself.

Whitey can jump higher than usual stickmen, outrun even demonic powers and push crates to open doors.
