You have a great game here but I found certain things that bug me.
note: I played as Reimu
-Marisa is too weak once you get to the higher levels (for me anyway)
-Shikieki is tough but doesn't do much damage to me and gives too much exp. I mean I got from level 20-30 to 50+ just by versing her all the time.
-Non-Ex dungeon bosses are too weak once you get to 20-30 level or less.
-I can't recruit Sanae.
-What do you do with the fishes?
-Keine learning goes beginner, average, average then nothing.
-I can't complete Ex-Dungeon 2, even tough I followed those direction.
-Shows an error when trying to go beyond the graveyard north of town.
-Can you do a better hint for the Tea set quest.
-Oh and you have certain glitches in the houses of Aya, Yukari, Marisaand some more I can't remember.
Those are the ones I can think off top of my head.
