Eh.
Don't get me wrong, it's a good game, and I do like it a lot- it's just, there's a lot of stuff that's not so fun in it. Some of the songs were a bit too long- The trick to music games is to have fun, short songs that are catchy and can keep peoples attention. Also, it was a bit confusing with so many keys to press, and the fact that you could get your score really high on the easy parts and then let everything else slip yet still get a good score.
Overall, good game. Keep trying!
