Wow, I played like utter shit right there. I attempted EoSD lunatic, and started the run with a bang by bombing Rumia's opener. Long story short, bomb spamming, dying with bombs in stock twice in stage 5, and somehow still reaching Scarlet Meister. I should just cave and start playing max lives again (since bad endings really leave me down), but then it wouldn't be as satisfying.
I think I need to learn to play with Marisa A. Marisa B is great for getting through the game, but I care about making good runs now, and hellish Patchy battle aside, I think Marisa A is worth learning to deal with her tiny range.
Still...I felt like the knowledge that there is control lag made me screw up more.
