Only complaint I have to give to this so far is the difficulty scaling between 4 and a half to 5 star difficulty. I can swim through 4 and a half, but 5 star is all of a sudden "Thou must fail the first 30 seconds". I mean, I'd understand a FEW maps doing this, but this happened to me with maybe about 13/15 maps. And no, I did not choose an Insane difficulty song. Just hard mode 5 star... granted difficulty can be mislabeled, but I think I made my point regardless.

Other than that, I just use no-fail modes to practice anyways, so it isn't too bad of a problem.
