Very good atmosphere, it felt tense and gave a strong sense of vulnerability.
I tried playing with a gamepad but found that it was really difficult to crouch and move at the same time, more so if I ever had to change directions by looking left or right. If it were a toggle instead of holding the button I feel it would help a lot.
That said, once I actually encountered the Turned I realized I didn't have to worry too much. They were easy enough to run away from even when they were in blind mode instead of deaf mode. :D
It took a while to find and activate all three terminals, everything is very dark (as is intentional, I'm sure!) I also did get stuck on things twice, once in the starting area and another against a random wall. I also accidentally trapped myself in a locker at one point, I couldn't get out until I switched from gamepad to using the mouse.
