Pros:
- Great music
- Great visuals
- Simple to play
Cons:
- Missing any indication that you're actually attacking in any way.
- It's very easy - Could either speed up the buttons quite a bit, add more buttons to press, or make the opponent increase at a faster rate.
- Notes don't match up with the music, but that's probably difficult to do.
Overall it's an enjoyable, if short experience. Great work!
