Sigh... I've actually "defected" back into Pokemon. Every single Touhoumon edit is a huge pain to play through.
You can always try Moemon if you want to change a little: no differences aside for the sprites.
I agree with the part of the pain tough. If I really want to play a nice and relaxing Touhou RPG, I'll go with Pocket Wars. It doesn't have every character, but at least is much more forgiving and easier (but it isn't balanced at all, there are some OP character there too).
