Help the little ghost to find the exit by solving puzzles and fighting monsters. In each of the 20 levels you must locate and reach the exit door by carefully exploring your environment and interacting with it. Collect keys to open doors, operate levers, use toolkits to repair broken objects, and reveal hidden items with your flashlight, among other actions. At the same time you must escape or take on various monsters that pursue you in different ways. Avoid them by turning invisible, destroy them by pushing objects over them, or blow them up with explosives. Each level features one or several unique puzzles that lead to the exit door.
