Glad to see that The Dead City was reviewed on AG. I played it a couple of weeks ago for the first time and I liked it a lot. I too agree that the puzzles were excellent. They weren't there simply for the sake of being there. I pretty much agree with all the other points made in the review, and it also did take me about an hour and a half to beat the game. Anyways, nice review, and I highly recommend trying out the game. It's a nice hour or so diversion.
