I've wanted this game for a while and finally got it from Club Nintendo. Keep in mind that I am a big music fan.
I enjoyed the gameplay mechanic of just using two buttons to play the game, but after a while it got very repetitive. There is a little spice when you get to play as other characters with other abilities but that happens very little. I felt like the boss battle were very weenie and most of the time even easier than the normal levels. This kind of threw me off a bit but overall the mechanics might have been a little repetitive but they worked very well and the controls were pretty smooth.
The games music was fun and enjoyable and was different for every level. I never felt like the music got annoying.
The story left a little to be desired. I was good but happened so fast you couldn't absorb it. I felt like it was too rushed to make any lasting impact.
The graphics were good and smooth. There was nothing about the graphics I didn't like except that I thought tempo was ugly. I very much enjoy the movie and story clips. Both were done very well.
