The concept behind the game is nice, the music is okay, and the art is gorgeous, but the gameplay itself can be erratic and frustrating. The sound doesn't always exactly sync up with when you're supposed to tap the screen, and even hitting notes when the "assist" glowing dot hits the circle doesn't always guarantee a hit. And then there are a few screens where there isn't any beat, and you just have to try to mentally time/guesstimate when the sequence is going to start, to try to hit the first note. Too often an exercise in frustration.
