Zero the Kamikaze Squirrel

Zero the Kamikaze Squirrel is a spin-off of the Aero the Acrobat games, its main protagonist being one of Aero's antagonists. The gameplay is similar to that of Aero the Acrobat games, involving fast-paced side-scrolling and platforming action. Zero can eliminate his enemies by executing his trademark Kamikaze Slam: spinning in the air and crushing the unlucky adversary. (mobygames.com)
