Announced at E3 2007, gameplay involves a mannequin figure traversing a rotatable world occupied by Oscar Reutersvärd‘s impossible constructions. The game is based on the Object Locative Environment Coordinate System developed by Jun Fujiki, an engine that determines what is occurring based on the camera’s perspective.” <wiki> <home>
