Regarding Resurrection Butterfly the only "trick" I've found is trying to position myself vertically so that I'm near the "breaking point" of the red waves. This makes it easier to dodge them without them crossing and getting messy and when the wave's ending I can always escape upwards to prepare for the next laser wave.
Also on rage:
ORIIIIINNN!!!!!!
I HATE her and all of stage 5 on SA, actually. Argh, THE RAGE! Even today I was making such a nice Alice run and then, boomf, stuck on Stage 5 FOREVER. The very stage is long and bloody bullshit, with EVERY SINGLE TIME THAT DAMNED CAT APPEARS being a nightmare... I've only made it past her once, actually, pushing Aya's bomb to the limit of effectiveness (and it makes MIRACLES, children!). Too bad by then I was tired and all and never got further than Utsuho's Evil Stars, meaning I can't even jump to it in practice (also, Stage 6 is another BS with that never-ending wave of streamers before Orin....). Top it all up with Utsuho's awesome music and SHINY SHINY spells making me completely obsessed and you have one VERY frustrated player....
