Taking a break from an essay, I played UFO stage 6. This isn't really an accomplishment, but it's no rage either. During the course of the fight, my performance ranged from screwing up the opener and still surviving, to screwing up Magic Butterfly, to capturing LFO without requiring any fancy dodging.
I love how variable my performance on this fight is~ The only control is that it's always fun.
EDIT: Just proved once again that it's possible to dodge Vampire Illusion's walls. I wonder if I'm really the only person to have thought of this?
