(Z,X,C,V,V). Notes start to scroll down the screen with the beat of the song and when they hit the bottom you must press the corisponding key. The game is easy to understand, hard to master. Here is a screen shot.

Note the screen is not done either.
Anyway, depending on how accurate you hit the button you will get a score and a "PERFECT" "GOOD" or "MISS". Each one adding to your score, or subtracting. At the end of a song, depending on score and number of Perfects, Goods and Misses you will get a letter grade of S,A,B,C,F.
I am really hoping for this project to go well, post any feedback.
