Pretty interesting, the power ups add complexity, but it might be too hard to keep track of some of them while you're trying to also decide if you're going to tick/tock the next beat.
Hearing your own rhythm was a nice touch and the timing was on point, it must've taken a lot of syncing.
Not sure if that's above or below average, but I made round 13 by just ignoring all the scoring, getting generic buffs that didn't depend as much on timing and order and hitting the right arrow key on beat.
