There is so much content here, and it's not just generic koi anims with mediocre writing stringing them together - it's genuinely creative and unique, there's obviously a ton of effort being put in here.
A really minor issue in chapter 2 - when Faust appears to advise that the girls are roadblocked until receiving the wish from Naruto, maybe he could specify which ones still need to progress? I'm sure this could be a simple check of their various states in the save file, which would get reflected in the dialogue when you talk with him.
Related note - to anyone stuck after giving Sarada the pills, and her story is not progressing - the game hints that you need to wait a few days, but I'm 90% certain it only 'counts' the days where you specifically sleep in your village house.
I spent a bunch of days doing other stuff outside the village, and when her quest didn't update after 5+ days, I assumed she was roadblocked and spent...way too long...scouring the map trying to progress the other girls' storylines. Maybe that helps someone.
