It's so funny how people find different bosses and their phases hard for different reasons.

I was so sure I'd never beat this robot. There was simply too much on the screen in his first phase, and when I'd get to his second phase, I didn't know how to even damage the flying head let alone kill it while avoiding bombs.

Well, the first time I beat the second phase (with a nuke and some follow up) I breezed through the third. It was insultingly easy. I find these bullet hell sections easy because you only really have to move up or down. Not so much weaving between them, as just moving the correct direction. I think wally warbles feather section was a harder bullet hell.

Now just cala Maria and her bullshit ghosts, and I'll be on the finale! Wish me luck!
