Really pleasant visuals and I like the atmosphere you've created with both your visuals and the audio. I really like the health bar/collar light thing, the colours convey health level pretty clearly. The music change when engaged in combat also feels really seamless and nice, I didn't notice it upon the first few enemies but still felt the vibe change.
The recoil on the gun feels pretty decent, it's enough to increase tension by making me worried about missing shots but it doesn't feel unfair or frustrating.
Starting camera speed is super fast both with keyboard+mouse and a controller, I played around with adjusting it in the options but didn't really manage to find the right middle point. To be fair that's in part because your QUIT button's area is so big and right under the camera speed slider, so I clicked it a whole bunch of times on accident when using a mouse. Controls other than that felt fine with a controller, I accidentally used the flashlight instead of shooting at times but I figure it's the kind of thing that varies person to person and I would get used to as I play.
