So, first: Really liked the game, hoping for more. Well made, interesting concept and cast.
Second: is high/low sanity a reason to get or not scenes?
I have done all lewd scenes possible (at least I think I did) before visiting Anabelle and didn't get the 'chance' to take a bath with her, but I have rewinded when I heard the "worm" when visiting the Hale's shack in the night with the glowing lights AND when I saw the fruits on Isaac's table, since both interactions struck me as "normal scenes that only add to atmosphere by lowering sanity".
...Or maybe I had too much lewdness going on for Anabelle to ask me.
