The atmosphere in this is very well done with great sound design and art and I enjoyed the game play a lot as well. It involved a fun mix of reaction times, resource management routing and exploration in such a simple game which is really impressive.
There are two minor things that I didn't like, one being the fact that the camera trails behind you where it would be much more useful to be centered on the play or to trail in front of them so you can see where you're going better and so you have more time to react to the faces spawning just off screen in front of you.
The other thing is the fact that sanity seems to be spent whenever you swap between light and dark modes, but you're forced to leave dark mode whenever a face spawns in front of you means that winning can sometimes feel like it's a little bit in the hands of the rng behind where the faces spawn. As you can lose a lot of your sanity because the faces decide to block the same corridor you need to go down 4 times in a row.
But at the same time I feel like these things may just be personal preference, the limited camera view in front of you can create good moments testing you're reaction speed for instance. I enjoyed the game a lot and I think it is scoped perfectly for a week long jam
