Tempo is a grasshopper with enough hyper energy to save the world of music from the evil doings of King Dirge. The dastardly king is trying to steal the rhythm out of Planet Rhythmia. It's up to Tempo, who has special "Sound Energy," to save the day. You'll fight by hurling musical notes at the evil troops or you can throw Tempo into his deadly spin attack. Tempo can't shy away from the difficult situations and areas, because once there he'll gain special power ups and additional sound energy. You'll listen to a great mix of rock, rap, and funk music that changes according to Tempo's energy level.
