This is a really cool idea! I don't think I've ever seen a game with this kind of mechanic, especially considering you have two simultaneous note tables happening at once (which I think fits the DJ theme perfectly). However, it was a little hard to control the pickups with the mouse, and, as others have already pointed out, I think having different keys control each pickup could make for an even cooler experience (maybe WASD for one and the arrow keys for the other, idk). That said, the visuals are cool, the music is cool, and the whole game idea is very interesting. With a little more work put into it (which I know probably wasn't possible during a game jam), I can definitely see this becoming a really solid game!
