Guise wat do.
(also, uploading as KounRyuSui brings me to an upload URL by... kakusei. =\)
Stage 1 - don't move around so much on Letty's first card, it's really unnecessary. It's an easy card anyway but...
Stage 2 - The last fairy wave before Chen can be dodged with a simple small tap left or right - I wouldn't try the all-the-way-around dodging on anything higher than normal, since it's usually a forced bomb at that point (though I find it easier to PoC that way on normal so yeah).
Stage 3 - I noticed you were moving a lot more than you needed to in Alice's midboss spell. Basically you can just sit at the bottom and watch the lasers - wherever the lasers are is where the blue bullets will be, you can just wait in one spot and move if a red bullet's coming at your face.
Stage 4 - You were close to an extend with 1 bomb and max lives - it would have been a better idea resource-wise to suicide before the extend and go to max lives 3 bombs. I also would have held off on that border at the start, since it doesn't do much for you there. Don't shoot the exploding things - max starting lives doesn't work in score runs anyway, you're just wasting bombs there right now. This goes without saying, but try not to pichuun 3 times between Lily and the end. The first two were because you didn't give yourself enough space, be a bit more careful with that. The last makes sense, but if you have trouble with that fairy normally I recommend bombing it. The death on Lunasa's opener... Uhh... Don't do that. First Prismriver spell is simple streaming. The yellow wave comes last, so make your dash for redirecting after that. Lyrica's second spell (assuming you go that route again) is all aimed. A small tap is all you need to dodge the bullets. I say practice the hell out of that stage.
Stage 5 - Everything in that stage other than the arrow-shaped bullets is aimed, so try not to move around so much in the first half, it just makes things harder on yourself. I recommend unfocused shooting on Youmu's first boss spell - there's no need to save your border for the nonspell.
Watch this for a how-to. Alternatively, you could also do it my way and
doge through the gap in the bullets on the second red/blue wave. Not sure what to tell you on the second spell's first death, but the second was reasonable I guess. Third spell is one of the easiest in the game if you stream slowly from left to right. You should never have to redirect it if done correctly, only look at the rice bullets.
Stage 6 - I felt bad for you on the double pichuns+bomb, dem nerves =(. Second nonspell is basically the same as Youmu's third spell but with nothing to hit you. Start left, stream right, (or vice versa) NDNBNE(ffort) it. Second spell? Ha, that one can go die in a fire. I honestly have no clue how to do it. You made me cringe on the third spell when you directed her stalker explosion thingy up, don't do that. I really have no clue how you didn't die after that >_>. Nonspell after that, blue is aimed, green is aimed away. Small taps man, you should NEVER have a gameover on that nonspell.
General tips: practice stages 4-6 more, don't be so jerky around aimed bullets, use your focus more when you're at the bottom unless it's an easy-peasy phase or you need to set up a border. If you're almost certain you can't capture something, break a border on it if the bullets are dense enough. Spell captures increase cherry item value, which is nice, but a break can also put you about 20-30k towards your next border if there's enough bullets (not to mention saving a bomb). Cherry max doesn't really mean much on a survival run either, so keeping a border doesn't help you at all in that respect - always break your border on nonspells. Of course if you're breaking a border near the end of a nonspell, you should probably wait a moment for more bullets to come onscreen before you finish it off so you can have your border ready for the next spell. Borders will save you man.
