Having the same issue I believe. There's only a couple of quests, from cleaning your room to the questions/interview from the librarian., and that's it. There's nothing else and no NPC's around, nothing to interact with etc.
I don't understand why everyone else is saying it's a wonderful game :s
I've tried redownloading it a few times with and without LustLauncher and nothing helps. I haven't seen anyone mention a fix yet either.
