Was this a randomly generated dungeon or was I being randomly spawned in the rooms? Either way great job on the sound design, flashlight mechanic, radios etc...
My only criticism is the rats you couldn't do anything about them and they would push me out the map, I tried using the flashlight but nothing worked.
Another thing I think would have helped would have been a ray interactor or similar, I had trouble picking up the torch of the floor as I just couldn't reach it.
Overall it's a great game idea and I think if it was polished it would be really fun!
