Decent game, plays well. Not sure how I feel about some of the classical songs "techno" backbeat.

Also, I hope the IAP system in place works out for the developers but I myself prefer to spend real money on songs with this type of game, spending real money to play period... Not so much so. Two suggestions for fixing this would be 1, have keys slowly regenerate or 2, set the price alittle higher and let it unlock unlimited play.
