update: I have made this fight significantly harder and flashier after this. I love it so much but it's soooo hard, i don't know if people will like it (i like it BECAUSE it's hard now). but i don't want to change it! watdo!?
You might want to watch this on an oled screen. It's pretty dark.
After a, I don't know, 5 years hiatus, I'm back to work on my megawad. Reworked this boss a little bit to be less of a bullet sponge and way more aggressive and agile. It's a lot more fun to fight now!
Still needs some tweaking. His spin attack is way too strong as is.
