Reminiscent of Marble Madness and Labyrinth, the objective of the main game is to guide one of four playable monkeys (AiAi, MeeMee, Baby, and GonGon) encased in a transparent ball across a suspended series of platforms and through a goal. By moving the analog stick, the player tilts the entire set of platforms that make up a level, called a floor, and the ball rolls accordingly. (wikipedia.org).
