Once I got into the swing of things, this was really cool! I absolutely loved the solo coming out of the arrow keys, I spent a minute jamming in the tutorial just to listen. Also, a tutorial! That was a really helpful thing to include, and impressive in the span of a jam game. It did seem that all of the enemies taking 2 hits was pretty hard since enemies could pile up a bit - maybe sprinkle some harder enemies among one-hitters since attacks only happen on a beat? Overall great entry, I enjoyed it :D
