This was so amazing!!! I love rhythm games and this stole my heart. Props to your friend for allowing you to use their amazing song as the default! I also loved the ability to insert songs, that's so cool! Even though the charts are a bit wonky, I'm sure they'll be even better being trained on more songs! I love that you made it clear when we got good, okay, or bad notes with green, yellow, or red colors, but I would love to see some color for missed notes, too! Maybe faded or black? It would also be nice if a pop-up saying what kind of note you hit came on screen, though that's maybe because I'm used to rhythm games having that haha. Love the chill environment with the background, and I hope to see you add more cool features in the future! If you keep working on this, maybe consider different difficulty levels, at least for the default song! I'd really enjoy that.
