Loved the atmosphere and premise, but the combat could get pretty frustrating. The gun felt painfully weak against the monsters, which kind of undermined the premise when, because I was playing back-pedal/keep away with the monsters, I wasn't really convey the feeling of paranoia I would have expected. This issue was worsened by the fact that (I'm not sure if this was a bug, or what was happening) I discovered that I couldn't die. Or if I could, my health pool was so ridiculous that even after intentionally standing in a fire geyser while being attack by a swarm of 5 aliens, I was still not dying.
I would strongly recommend shortening the time to kill of both the player and monsters dramatically to give that feeling lethality and paranoia this game should have.
