8/10 (Five bananas out of five, but only if you stretch first).
Every time you hit an enemy, smash a crystal, or grab a banana, a combo multiplier ticks up. If you go more than a few seconds without hitting something, the combo resets to zero. To clear a level, you need a specific number of "Beat Hits" (basically, score).
This version utilizes the Nunchuk and Wii Remote.
