Really well done game!
One thing I will mention however is that I think the walking speed is a little too slow, but I understand that this adds a form of dread. Otherwise maybe at the end have a button to go back to the menu, since I believe I had to Alt F4 the game to quit it. Or maybe there was a button and I was just blind lol
While I can relate to the fear of a stranger being in the attic, I had/have the fear of someone being in the basement.
