Three Shades of Gray is a 2D survival shooter. Your task is to repel the attack of as many ghosts as possible, each of which can be one of three shades of gray. The difficulty of the game lies in the fact that the shade of the ghost can coincide with the shade of the background surrounding you: use special light traps to identify such opponents.
