The fights in the final zone take forever. That being said, the real problem is the nonexistant AI. It REALLY should be possible to control your own guys.
Great animations and moves, no so great fighting. You either kill them with the first move, or you lose a lot of life. Bosses are too hard/normal levels are too easy.
Bah. Could be a great game. Play Lumenara on how to do it right. Enemies are so fast that aiming is basically impossible. Also, dying within the first second of a level isn't al that motivating.
