A Game Boy port of the title was also fully developed (by Damian Stones, of Climax) but was never released for the same legal reasons as the Super Nintendo port. In the single-player game, the player controls Mick or Mack through four worlds; Slime World, Mystical Forest, Toxi-town and Arctic World. Each world has several sub-stages where the character must collect a certain number of Golden Arches to advance.
