The song is awesome, good job! And you did a nice job arranging the elements beautifully. The presentation is pretty flawless here. The gameplay is simple, but it works really well and fits the theme of this jam. And you did a great job of mapping the keys at the right times.
I feel like the sound that plays when you hit the notes is just slightly delayed/off. This is especially apparent at the strings of 4 eighth notes in a row. That could just be because of the way it's embedded in the webpage, though. Or maybe it's a skill issue on my end 😅.
Either way it's an excellent entry, one of the best I've played here.
