Good game, I like the concept of switching lanes to the one that has the note in order to hit it!
Some feedback I would give for this game is a way to change scroll speed in case it scrolls too fast for the player, and changing the hold note’s color so that players would recognize it easier.
Additionally, I think it would be better to put the game explanation within the tutorial level at the level select menu instead of having a separate “How to play” button so that people that want to get right into the game can get themselves started!
In any case, great job on this game!
