Phantasm stage. How to do the PC98 crap. Lol I mean the last few waves before yukari. Seem to keep Eating The Bullet.
I assume you can do the first half of that part easily.
Here is my strategy for the second half.
The part with bullets coming from 4-way, 4-way, 9-way.
you stay 1/4 from right, 1/4 from top, unfocus move straight down, move left, and then move up (like a U shape).
You move only after the shots fire.
Each time you move roughly 1/2 of the screen (so you should be 1/4 from bottom+right after the first one, and 1/4 from bottom+left after the 2nd one, and then 1/4 from top-left after the 9-way).
The last 4 waves (after above): stay roughly 1/3 from top and center. Move down, up, down up, each time moving 2/3 of screen.
Timing is harder here. Just watch a replay.
This is going to sound really stupid; Meiling's stage 3 mid boss non-Spell Card on Normal. Can go through Sakuya without using a bomb nor a life no problem, but I just can't manage through that non spell, whether I die or live through it seems awfully random.
You have no problem perfecting Sakuya (even I failed that, in previous weekly tournaments)?
Then that non-spell should be piss easy then. Stay at the bottom, dodge blue bullets, go through red ring, repeat.
