Great Imitation of O2Jam
Personally, I'm a hardcore fan of the real game O2Jam (although I'm only lvl 27). The server apparantly broke down for a long time and I found this game. Thanks for relieving my cravings for the game. The gameplay is exactly like the real game, except for colours and such. What I don't like is only the highlight of the notes. Other than that good job, and add more songs and functions (choose own speed like in O2Jam).
I vote you a 5 and a 10 for ratings!
