Players control Congo, a half-monkey, half-human kid who must rescue his girlfriend, Congette, from a demon. The six themed worlds are each broken up into four stage pieces consisting of jungles, valleys, volcanoes, rivers/lakes, a pirate ship, castles, and even the insides of dinosaurs. Using a club, Congo must battle Fuzzyneck cavemen and flying Pteranodon while navigating past stage hazards, such as moving flames, spiky balls, and pits.
