I've been playing these games for over six months or so. I've only recently been able to 1cc anything on a semi-consistent basis. On Normal. The only Extra I can beat between EoSD PCB and IN (haven't really played the other games at all) is IN. PCB's in particular is pretty overwhelming for me. I've never even made it to the boss and the midboss embarrasses me horribly (and to think, some people can do it in one try.)
People saying they suck when they're so much better than me makes me look like a chump.
Hey. Hey. Hey.
I am quite legitimately terrible at Touhou.
You beat the IN Extra, and I can only get to Fujiyama Volcano.
Also, UFO and SA are arse. If you're a Normal player, than Easy is around the difficulty of Normal in IN.
As for the PCB extra, it's pretty much ALL ABOUT STREAMING.
Wave 1: Aimed. Micrododge to graze for score.
Wave 2: Not aimed. Don't screw yourself over.
Wave 3 and 4: Aimed. Micrododge to graze for score.
Try to take out these fairies early, before they shoot off everywhere.
Move to the left. Shoot down the fairy with spinning bullets.
Move to the right. Shoot down the fairy with spinning bullets.
Repeat three times.
Fairies will appear with aimed bullets, although one isn't aimed, while rows appear at the top.
Shoot them down early, they drop ~30 Points. When they stop shooting, they move off the screen via the side opposite to which they appear.
Wheel around their bullets.
Chen's Nonspell- Don't move until the bullets stop firing.
Nudge to the left. Repeat.
As for her second pattern, try to find an area that allows you to dodge both waves at the same time.
Nudge upward to avoid the blue bullets
after they stop firing.First Card- start at the top or bottom, stream downwards, dodging randomspam. Stream upwards the next wave. Repeat.
Second Card- Hard to explain- I have a very specific method of capture for this- and I don't recommend it
Post Chen is really a repitition of the past stage bits.
At the end, there's a large cloud of randomspam fairies and death circles. The death circles are aimed, and fixed, so they should be easy to avoid the first time you go through them.
Good luck~
