Toki

Toki is a 1989 shoot 'em up platformer arcade game, or a "run and gun", with elements of tongue-in-cheek humor combined with the action. The player takes control of an enchanted ape who must battle hordes of jungle monsters with energy balls from his mouth (described humorously as "monkey-spit" or "monkey-vomit" by many gamers). Your ultimate goal is to destroy the evil wizard who cast a spell on you; therefore transforming yourself from an ape back into a human, and rescuing the kidnapped princess. The game was later ported to several video game consoles and home computer systems. (Wikipedia)
