Cute concept! I wonder what the score means in the gameplay. I like your design choice of making the two tracks slightly different and making people try to match them. It kind of implies what DJs do; it's really smart!
I wanted to design a more complicated score system to show how ppl feel about the music, but I ran out of time :( So the score system now basically checks if you are playing 2 tracks and if the BPM of the two songs match
