SA Normal 1cc. ReimuA.
Every Extra stage unlocked in the Windows games. For normal, I still have to beat PoFV and SWR.
It was the first time I reached Orin, and I couldn't understand what to do on any single one of her attacks. Constantly walled by the ghost wheels, shooting zombie fairies in her first spellcard, NOT shooting zombie fairies in her last spellcard, can't read her non-spells worth a damn, etc.
At least it's pretty easy until Satori. I died once or twice to her, a crapload of times against Orin, and twice to Utsuho I think (a non-spell and her last spell). I also got stuck in Heaven and Hell Metldown. I was near the left wall and I kept dodging vertically all the time, so I didn't do enough damage to capture it.
