What a cool game concept! As a fan of TD and rhythm games, I think it was awesome that you combined the genres. Even though I wasn't very good at it, I still had lots of fun trying. I was a bit overwhelmed by having all three tower types at the very beginning. It would have been nice to just have the yellow tower for wave 1, then add a new one during the subsequent waves. Also adding a latency calibration would have been great. But as an artist, I have no idea how difficult that is to do, and fully understand that it's not available in jam game. Overall though, I really enjoyed your entry.
