Devil's Heaven

Devil's Heaven is a vertically scrolling shoot-em-up. You play as a devil who wants to take control of heaven by force. In each level, your aim is to reach the next rainbow located further into enemy territory. You are opposed by increasingly dangerous opponents from the angelic horde. Colliding with any of heaven's denizens or their projectiles will lose one of your lives. When all three are gone, the game is over.
