This is a clever idea without making it too complicated. I'm a bit rusty with rhythm games so it took a few attempts before I got in the groove. Once in the groove it was very addicting, having the spells fire on beat also made their SFX mix with the music quite well. One thing I missed from similar games is a more clear beat indicator, makes it less likely that I fall into an off-beat spree,
The game runs without issues on Linux via Proton, so that's a plus!
