Very much liked the base gameplay and idea! My main points of feedback would be that some more feedback for hitting a note correctly would be nice, like an effect, and having it disappear when you hit it. Other than that, I feel like some more general polish would've added a lot, however besides that I think this is a super cool entry! Really neat that you have a leaderboard as well! I feel like the improvising mechanic was a bit too punishing, but that might just be a skill issue on my end, either way, music was really good as well, great job!
