The only things wrong with this game are Yamame's first pattern, the second half of stage 2, Satori's Yukari cards, and the stage portion of stage 6. Which might seem like a lot, but in the grand scheme of things, this is a kamige.

Well, the main game is, anyway. I actually find the Koishi fight in Extra to be possibly the least fun thing ZUN has ever made, but I don't really care about Extra.
