I liked the atmosphere here :) it seems like you added a lot of customisations too, good job!
I noticed you mentioned something about audio volume not being consistent and a bit loud - I find it helpful to normalise all my sounds to -1.0db in a program like Audacity before exporting them into my game engine, you might find that useful too!
I think I ran into a small bug where the flashlight angle ended up vertical after equipping screwdriver and then back to flashlight :(
