Very nice work! The atmosphere was done really well, especially the setup at the beginning. I feel like I don't typically get spooked by games like these anymore, but this one worked on me! [SPOILER COMMENTS AHEAD] I can see your inspiration from PT with the door trick. It might be improved with a less vague story- it might have been cool if you took some inspiration from The Babadook with regards to the (difficulty of) motherhood theme to give the game some more weight. For me, once the monster stealth / avoidance was introduced, I felt like the game got a lot less scary, since it somehow felt more familiar and video-gamey. It could have been cool to play with more of the environmental effects / scares, and make the antagonist less easy to visualize to leave more up to the imagination. Anyway, pretty awesome, high quality, stuff here!
