I found this episode quite difficult to solve and I couldn't finish it without watching the walk through. First, I wouldn't expect to turn over the compass to find a clue. Second, I got a little confused about what to do next after getting a wrench because there were two issues at hand - the power panel was off and how to cross the water. It turned out I had to used it to get a board from the kitchen. Third, it took me quite some time to figure out what I could do with the black and golden keys. I'd appreciate if there were some hints for that. Testing keys in the darkness wasn't a fun thing to do.
