by the way, yup- the hold note situation is completely fixed! middle scroll works wonderfully too. the only small bug ive noticed is that the pause sign is on the side of the screen instead of the middle, but it doesnt affect anything lol. i think that may be a side effect of middle scroll. do with that what you will! i dont have a problem with it.
another feature you could add is Discord Rich Presence like psych engine did! i dont know how all that works, but im sure people would enjoy it. (and if you dont know what that is, its like how the game shows up on your discord profile. what song youre playing, the length progress of the song, number of misses, difficulty, whatever)
