Wow I love the graphics and atmosphere of this game! The style is very unique and the distortion really adds to the disorientation of the character. The sound design was good too, nothing felt too unbalanced, and the voices were perfect. The switch between settings was really well done, and I liked that the inside environment had a couple of dead ends that forced you to turn back and kill some enemies. That was one problem I had - the first time I played I spooked at the sudden appearance of the mutants and managed to run past all of them while also finding the correct way out. It was a breeze to get to the end point on that run, but a bit more difficult when I took the time later to try and explore the level.
I found killing the enemies to be a bit strange though; I think it was about 2 shots to down an enemy, but I could never hit them with the knife enough to get them to die before me. A bit more feedback for when hitting/hit would probably help this - it was hard to tell in the darkness if I had landed a blow, and it doesn't look like there was any real indication of how much health was left for the player.
Overall a really good submission that definitely stands out!
