Fun, but a few flaws.

Its a fun game, even with the lack of free/custom beat maps.
But, every once in a while the screen distorts a little after a song. I know at this point if I click retry or back, it will probably crash. Its not much of a problem, though.
My main issue is how your letter grade can go down when you get a new personal best. How do you get more points with lower accuracy? Ive tried hard to get Ss but then I replay a song I like and it lowers my grade down to an A, and then because that was more points, it makes it that much harder to get that S rank back.
