In the single-player platform game, the player controls Klaymen, a resident of the Neverhood who is kidnapped in order to prevent the destruction of the Neverhood. He can jump, duck, look up, and grab a wide range of items such as a halo (allowing him to withstand more than one hit) and a wide range of quirky and crude projectile weapons. Aside from the assortment of weapons, enemies and bosses can be destroyed by jumping on them, and there are several secret levels (set to 1970s easy-listening music) where bonus points and extra lives can be earned. The levels are in a sidescrolling format, unlike the point and click format of "The Neverhood".
