I really love the Out of Control theme being the spin and break mechanic! Doubles as punishment and a second life because you're invincable during it but you lose a note when you come out of it.
And multiple songs needing varying amounts of keys is a very good balancing mechanic. Powerful songs such as heal needing a lot while basic attacks needing just a few.
Took a while for me to get used to W actually moving diagonally up instead of straight up lol
Only real issues is how you can get seemingly stuck on the terrain quite easily and that the wind shield lasts so short that it's impractical to use as a parry especially since this is in a game where it takes non-zero amount of time to "charge/type" your attacks.
