You play as bat Aero , who have to stop the mad scientist Edgar Ektor, who is trying to rid the world of amusement and fun. So you jump through the circus-style levels, using different kinds of machines such as catapults, cannons, bubble machines, platforms, etc., collecting various power-ups such as cheese, soda, keys, clocks, etc. and avoiding lethal obstacles.
The gameplay is a mix of action and adventure, where you control Aero as he navigates through various levels, avoiding enemies and collecting items to upgrade his abilities. You'll need to use your wits and reflexes to overcome the challenges ahead, as the game gets progressively harder as you progress.
