The worst of the bit trips. Beat was excellent, Core was half decent, but this one just didn't do it for me. The main problem is that the music just didn't have enough sync with the game play. In the other games, especially Beat, you had to play totally in sync with the music. In this game, although the music is nice to listen to, it isn't a critical part of gameplay, and thats really what the first two Bit. Trips had going for them.
