The audiovisual experience is amazing, the music keeps me pumped and the visuals are straight up gorgeous. I have some gripes though. The tutorial doesn't have to be a wall of text, you could've kept just the controls, "the less hp the more powerful you are" and "press space to start", everything else is just unecessary information. Also I noticed most of the patterns (which there weren't that many of) could be dodged by just continously going in a circle. Furthermore, it would be nice if you kept the upgrades after dying - death is punishing as is, no need to make it even more punishing :P
But that's just nitpicking, I love the game and had a blast, good job!
