Good rhythm game

Its a good game but it crashes way to often. I played for 10min then levelled up to level 9 and have 15000 gems. The way the notes curve are annoying. Its impossible to do jackhammers and jump stairs without crossing your eyes because of the curve. Meh its Mobile I guess its the best. I shouldnt expect much for a mobile game. If I were to compare this to other mobile games I would give this 10/10!

I cant find a nickname :P about O2Jam U, v1.6.0.11
