I love shmups so my ratings are totally biased 🙃
My only real complaint was that I wish the attacks for the Crab Pulsar had different sprites, so I could tell if the attack was going to be a beam or bullets. I spent that round trying my best to camp out in a few spots and not move at all.
Beyond that, every death felt like a skill issue instead of the game being unfair, especially Sagittarius A. I managed to weave in-between the bullets once or twice and that made me foolhardy enough to try several times more 🫠
PS - I also kept expecting graze mechanics and got way too close to bullets, but that's entirely a me problem...
