A rarity in Holojam: This game might actually be too easy! Which I'll definitely take over too hard! (Take that with a grain of salt though, it's coming from a touhou player.) The tutorial does leave out some important details. Fortunately I learned them from this comments section before playing.
I think it would benefit a lot from a score counter, as it sits you can just sort of float off to one side and occasionally switch colors until bloop appears. (and is it playing... halloween music?)
I do like the UI in the tutorial showing you the buttons you're pressing. That was a nice touch.
Switching colors to avoid certain patterns and fight certain enemies is a cool idea too.
