Awesome game man.
I just played a few songs and it really does get intense. I like the style of the game, but it took me a while to get use to the game play for the songs. It's not common to have a DDR version like game having to look from the right and then from the left.
Also, It would be nice to hear a small buzz or something if you hit randomly or you hit a wrong note. It's too much of a casual game especially on the easy songs when you don't hear a buzz if you hit a key too soon or too late.
Really good song overall though mate. I look forward to playing it more often later.
