For example, let's say that big red 'up arrow' key is approaching you from the right. When it gets aligned exactly with the beginning of the sheet music, you must press corresponding key on your keyboard. If you do it right and on time, you earn points. In the end, all points get summed up and you get to see how well you played and whether or not you have become ready to play with the professional musicians.

All that time while you're sweating and trying to keep up with the song, little stickman with a guitar is standing down in the corner doing nothing. Ok, it's not like that. If you do everything well for certain period of time, stickman will start running, jumping, playing guitar, surfing and what not. If you performance is bad, he will just stand there still, disappointed.

The best part about this game is that notes are perfectly aligned with the music tones, so you are actually pressing button in the rhythm of the song, which is kinda cool, especially if you prefer rock music.
