Spoilers ahead
It feels a little too easy to bump into stuff, it feels like there's not enough room to escape the monster chasing you unless you're really accurate, though I appreciate the ability to run and close doors. Maybe add checkpoints in any future release?
I did feel scared though. Like in Amnesia, especially hiding in closet.
Edit: On my second playthrough today I got to collecting the chemicals and water (I like how they just appear lol). The monster got stuck in running animation which was helpful and also clipped through wardrobe and walls (they have an annoying growling sound!) Also the game freezes momentarily sometimes upon touching the monster.
The ending twist was sad, but at least you "cured" the son. It reminds me of the game Notes of Obsession. Also I liked the low res graphics.
