her focus speed is too fast for me to control effectively
WAIT
You perfect EoSD Extra with MarisaA and now Sakuya is too fast? :V
Sakuya is faster than Marisa when focused, and also PCB Lunatic has much, much denser bullet patterns than EoSD Extra. The difficulty in EoSD Extra is not so much dense walls of bullets so much as that shit flies at you really fast from different angles, like Catadioptric or QED. :V
Having said that though, I just attempted PCB Lunatic with Sakuya A, and despite wasting something like fifteen-twenty bombs since I didn't deathbomb in time, I still managed to reach Yuyuko's third spell card before getting a game over.
Hmm. Still undecided which one out of Reimu A, Reimu B or Sakuya A to keep attempting with. In all honesty usually I use none of those three and stick with Marisa A, but I don't think I'm quite good enough yet to net a Lunatic 1cc with only two bombs per life.
EDIT: I decided I may as well give it a try with Marisa A, so I did that. I lost lots of bombs to not deathbombing, I reached Yuyuko, and then I game over'd.
...Goddamnit, am I going to have to go through this with every shot type before I actually get anywhere? <_<
EDIT, again: I just tried with Sakuya B, and failed at midboss Youmu after dying with four bombs in stock
four times in a row. I am not going to try this with Marisa B. <_<
