Very moody piece, nice creepy art. Basic horror tropes executed well. I liked mother's room being very different graphically to most of the house.
Even though it's a horror title, it may be worthwhile to give the player the ability to get a happy / success ending if they make the right choices, (though this is of course based on your own personal taste). I tend to prefer a pastel, optimistic horror, so that's not an objective critique by any means.
