This is a great game, nicely polished and has high replayability. I think the replayability is really boosted by the leaderboard. I also have the current high score, 34.58!
I ❤️ the music and I ❤️ it more knowing that you created it yourself.
One minor thought is to consider if guessing wrong should give the user a time penalty. Like 1 or 2 seconds.
