The new version fixed all of the stability problems I was experiencing on iPad 1. It seems they also made some of the patterns a bit more like the way they sound. Complex/long runs seem more achievable.
This is a really neat game. The graphics are really nice, the story is campy and fun, the English voice overs are so bad they are good. The music is decent, and includes some time signatures that are rare in this kind of game. Its really fun to play a song with a mixed meter for a change!
I am looking forward to the sequel.
