Yeah, I think the anticipation to finally get to grandma is keeping this game way ahead of others. But it also helps that the other characters are interesting too. I espacially like your family in this game.
Just the part with your girlfriend in the cellar is kinda strange to me.
I really like a game with some Tomboys, although for my taste the Tomboyish Features could be a bit more dominant. Would be cool if more games had those traits.
