I played Touhou games on Easy by default until I got SA, which I figured I could try at Normal since I was a hard mode player by this time.
Got SMASHED by Orin, so went down to easy, 1cc'd on my first attempt, went back to Normal and managed it the second time.
UFO came out, tried it on Normal, got to Shou and got violated. Couldn't win after about 6 continues. Restarted next day, got past Shou, got to Byakuren, was destroyed. 6 continues, can't beat her. Next day, restart, get to Byakuren with 7 lives in stock, finish 0/1 blind capturing Fantasia. To this day, I have no idea how that happened.
When TH13 comes out, I'll be starting that on Normal too.
