At the lowest level, White Belt, enemies are generally sluggish and non-threatening. At Black Belt, the game is as challenging as any of the classic twitch games. As play continues and more enemies are defeated, a belt meter in the lower left-hand corner of the screen increases gradually from 0% to 700%. Each belt color is associated with a multiple of 100%, beginning with the white belt at 0%. As the rating increases, so does the difficulty and speed of the game, as well as the scoring. If a player loses a life, their ranking is decreased, possibly causing the belt level to drop a color. In this way, the game tries to keep pace with each player's ability. In general, the player must complete 20 rooms without dying to be able to move onto the next color.
