Especially about the puzzle where you attach the rope to the broken wall to climb down the snow wall. The thing with the hook made absolutely no sence. You can just tie it to one of the broken pipes. I know it's hard to code, but I mean come on.

Then it was after using the short-wave radio. Where the worm breaks the roof in the ceiling. I would check there eventually, but I found another level door. Some form of sewer level I was guessing. I thought for sure that this was the place where we were gonna redirect the ice-cold water, but I was completely wrong appearntly. All it had was a wheel puzzle and nothing else. A completely pointless area. Why is it there?
