For some reason, this reminded me of the movie “9”. I really felt small and like I had already lost. You created a nice, tense atmosphere, but the map needs to be more densely filled—right now there are quite large empty spaces.
It would be great if you added sound settings and an option to toggle crouch instead of holding the button.
I also noticed a small bug: I approached the console and then ran away when I was spotted—the "E" prompt stayed on the screen even when I was far from the console.
But overall, I really enjoyed the experience. We are waiting for the release :)
