Some seriously good Bullet Hell!
The first half of the fight is a bit too heavy on the redirecting of bullets
But that seems to be fixed in the Ultra mode, making it more complicated redirecting.
The fight really shines in this second half, where you get some spells that are really good at abusing how hard you can macrododge thanks to the unlimited speed.
There's that attack to the right (2nd picture) which is some extremely fun to macrododge stuff.
I was a bit sad about the final attack (preeetty sure it was the final attack, but maybe I am micing up the penultimate one with final) being rather basic in comparision to the previous ones as it's basically the aforementioned attack with more danger to the side, which makes it harder but not really in an interesting way and mostly just makes it less fun.
I haven't finished ultra but the first half already seems a lot more interesting than in the original, I might try beating it when I am less sleepy to see what else there is in store.
