You play as two cartoon cups that lost a gamble with the devil and must now work for him, fighting several and very diverse cartoony bosses.
The game is heavily inspired by classic cartoons from the 30s (especifically the ones by Fleischer studios like Popeye, Betty Boop and Bimbo the Dog), but it takes it a step further by actually consisting of traditional, hand drawn animations and backgrounds put into the game.
