Oh some of these things gave me real chills! Brr.
I love it that you actually did voice acting! We were considering it for the intro of our game but ultimately cut it due to lack of self confidence and time :D And also kids sleeping upstairs.
Good work with sounds in general.
Cool levels with pipes and cables. Did you use splines/paths for the cables? One thing that could have been better was the super thin walls. They were almost planes sometimes.
In the end I was wondering if I would have to face the voice that could be heard every now and then, and especially during the escape. Phew, I didn't :)
Cool game, I liked it. It was immersive and well designed I think. Perfect length
