Thanks, I'm glad you enjoyed it! We didn't want to emphasise the current situation too hard when we were considering the narrative and world of the game, but it was definitely present in our minds as we were making design decisions.
The shooting through the walls was one thing that I never got round to fixing, but it never occurred to me how much of an effect it would have on the difficulty of the game. I'd just walk around and not shoot things unless I had a clear line of sight during play testing!
