Thanks for the feedback! I'll make sure to note it down if I continue with this game. Perhaps making textbox static with the pointer just moving along could help.
As for knowing which note is correct: the answer is hidden in the background music, so needing to read music isn't completely needed (but still helpful :D )! That's also why the music just looped, so the player can keep listening to it and try to hear if the note is in there/harmonizes with it. I guess I'll have to make that clearer as well next time around 😅
