You control a hero who has a phantom twin, his alter ego. When the hero moves, the alter ego moves too in a mirrored fashion. In some levels the movements are mirrored horizontally, in other ones they are mirrored vertically. You can switch between the hero and his alter ego a limited number of times per level.
