Good, but with some problems.
First off. You should put up a list of the songs. I like them. I had to get that out. Come lvl 7 and 8 (that's as far as I get before getting frustrated) the ball gets going pretty fast. But we could be going back and forth with nuke hits, but all of a sudden, he hits a nuke shot and it goes at about the medium hit speed. Is this a type of deception to throw it off or is it a glitch at work? I could get a good rhythm going and all of a sudden,nuke hit, medium speed. I think you could add some cool stuff to this game as well. Maybe a create-a-character. Even upgrades, like higher chance of nuke shot, longer bat for better accuracy. Just ideas, but I think they would help. Good game though. I enjoyed it.
