A simplistic 2-player game. Each player plays a spiky-haired guy that can jump really high. The objective is to jump on your opponent's head as many times as possible within whatever limit you decide upon (since the game simply goes on forever). Jumping physics are okay, though it's odd that you only get points when you actually start a jump from the top of the other guy's head (so if he moves out from under you before you jump, the point is denied).

It does look quite nice, though - being the first game to use SMZX Mode 2.
