Bite me, blind runs with horribly balanced characters that feature unusual shot types is not easy. Nor are half assed lunatic runs where you don't give a fuck, but that's besides the point.
*sidenote: those weird looking walls in stage 2's boss cause bullets to "bounce". You can fly right through them as I found mid video. On higher difficulties you may have to stay inside (wouldn't be the first time they pulled this one), on normal you can just avoid them completely and make the whole boss a complete joke. Also, the trance can be activated by filling 3 gauges and hitting the trance button. No idea yet what that does, aside from making you a lot more powerful, temporary invincibility, and SCORE OUT THE ASS.*
