This is so cool!! In our brainstorming session at the beginning of the jam I also thought of some kind of music loop reproducer game, this is basically a great implementation of that idea! Very simple and straightforward but well done!! Love the audio effects, UI style, animation, just superb! I could easily see this game extended to diff kinds of musical instruments (only got to lvl 7 so i might not have seen all of them, but by 7 there are a lot of sound sources already which is neato). Great job!
