Aero the Acro-Bat

Aero the Acro-Bat is a Super Nintendo and Sega Genesis game released by Sunsoft on October 1993. It was created by David Siller (of Maximo: Ghosts to Glory fame) and developed by the now defunct Iguana Entertainment. Inspired in part on the "mascots with attitude" feeling that was common with characters like Sonic the Hedgehog, it featured a red bat named Aero, who works and lives in a circus. He must defend the circus from an evil clown called Edgar Ektor, who used to work in the same circus and wants revenge, and his sidekick Zero the Kamikaze Squirrel.

The levels are played in typical 2D platforming, but in order to clear levels, the player must accomplish certain tasks so that the exit warp can be revealed. Those tasks include passing through hoops, step on platforms until they disappear, ride roller coasters, etc. There are 4 worlds with 5 levels each one, and the levels are big, many of them with some awkward positioned spikes that kill instantly.

Aero can attack by shooting limited stars, or by doing an aerial diagonal drill attack at his target (when he is in the air).
