Solid, from the handwritten help text at the beginning over the audio monologue during the walk to the arrangement of the furnishings. I solved some puzzles but then the light went out and all my batteries were used already. Good atmosphere.
In hindsight, I did not even see half of the assets you used. In my opinion the whole "short flashlight runtime" is an annoying element in horror games which only impedes players playing the game. With a working flashlight, I would still be playing it but for me it makes no sense to start a game anew only because the Dev thought it would be a good idea to put pressure upon me. It gets extra contraproductive when you integrate some handwritten notes which are important for the background story but in a small and unclear font that it takes extra time to read them. Your time limit creates incentives to NOT read your text and think about it afterwards - is it that what you want?
If you want to have the player explore the environment you have worked hard for, give him time to do it, layered by some ambience and maybe the right disturbing music. That sets the mood better than "Oh I have to rush through because I am out of batteries!" But that's only my opinion.
I got a permanent message in the upper left corner about the game not being able to provide all runtime point light shadows. This is probably because my testing laptop has no strong graphics card - the message appeared in "high" and "low" settings nonetheless - but of course this message does not belong in a production version in the first place.
