Sinfire Titan :With which character out of curiosity? I've been trying to 1cc it with Marisa A to no avail so far(altough granted I just play it very now and then).
Actually as Marisa A.
Conserve Master Sparks. The Speed penalty they apply makes it nearly impossible to get UFOs in a timely maner (makes it easy to tear up big ones though), so save it for when you are about to die.
I used up 3 bombs prior to Murasa (once on Kogasa's final spellcard, twice on Ichirin with one being a Deathbomb). Murasa's stage is perfect for gathering UFOs in large numbers, so use that to stock up on power ups and spellcards (and lives, but don't go out of your way to get those since it will get you killed really easily and because
Nue gives you one).
Once you get to Stage 5, be prepared to bomb like crazy. Don't start dodging Naz's and Shou's lasers, wait for them to point directly at you for the first couple of spellcards (they shift directions if you keep moving around, but once they go straight at you they stop moving).
For Shou's last card, stay near the spawning point. Her lasers don't veer towards you the way the first few spellcards do, but they are fairly easy to predict and slow-moving. This was actually the hardest card to beat for me, but I got through it with a few bombs.
Makai is literally hell for UF gathering. You need to stay mobile and focus more on your hitbox than on the UFOs or enemies. Don't bother collecting UFOs until there's a lull in enemies (they stay for a while) and for the love of God don't try to collect specific colors (use the UFOs' natural bomb to clear the screen, it's more important).
Byakuren is simple if you've got a decent bomb stock (4+) and near max lives when you start it. Bomb through her spellcard if you see the bullets getting too narrow, and use your deaths to restock them. Pay close attention to your hitbox, because you really won't need to focus on hitting her too much (Master Spark eats her health fast).
She got me down to two lives and one bomb, but it wasn't too hard to beat her using that strategy (it was actually harder to get to her without dying than it was to beat her).
