I think this is the highest budget crossover the game ever had, Completely new stage, character and even stuff like hearts, notes and ghosts were changed, only thing is missing is an elfin to go with, haven't seen a new one in forever
I mean it's ZUN he probably went out of his way to help make the characters himself, also only thing is there aren't many things that fit Elfin, maybe the inching or Auun but that's about it
Why did you not do all of them on master I have the touhou dlc (night of nights not included) and I can tell that master is definetly different and harder but it's more fun aswell
