Tempo

Tempo is a grasshopper who lives on Planet Rythmia, the world of music. Unfortunately, the malevolent King Dirge is trying to steal all the rhythm from the planet. It's unclear as to how a creature with no appreciation for music became King, but it's up to Tempo to stop him!

Tempo's game is a side scrolling platformer with 7 levels. It's a single player game, although you can collect "dance" power-ups that allow you to call your friend, a butterfly, to help you defeat your enemies using killer dance moves.
