I was able to play it for a moment and I loved it. And then it just erased itself.   

Kind of disappointed, because downloaded this expecting I could hear more Vocaloid songs, but the Vocaloid songs are limited (at least those that I know), mostly need you to trade first before you can play the song. Had the urge to uninstall shortly after playing it.

Good game with a lot of potential. However, offset keeps changing and is not stable while playing. Can become +20ms at one point and in the middle of a song becomes +200ms. Don't fancy the extremely short songs but it's a new game so give it some slack. Will wait till the game gets more polished to continue playing.
