Floating down rivers in an inner tube is the name of the game in this quirky action title ported from the arcade. In an overhead perspective, the shirtless player (in sunglasses) will maneuver downwards to reach a whirlpool to move onto the next stage. Many obstacles/hazards will get in the way, such as animals, branches/logs in the water, and characters on both river banks who will try to stop you, like cavemen or jumping penguins.
