Such a cool game, really what a good job!
We also have a rhythm game in our submission that I'm pretty proud of for my first attempt ever at anything like it. Your game definitely gave me some inspiration to continue working on it.
Art, music, gameplay, all nailed! My only feedback is that the 2nd level is difficult to figure out how it works. Maybe some clearer instructions in the tutorial section would be helpful. Otherwise, A+ job guys!
