A very unique idea. I understand this is just an experiment but I wonder if after all these years somebody has managed to implement this into a full game. Even as a bare bones test, it is surprisingly functional and fun. However, the whole "boxes fall in tune with the music" thing does not work all the time. I feel this might be because of the 36 box limit, thus breaking the beat and getting the engine confused. I dunno. What you have here is good overall.
