I find your comments about W7 interesting. It is rare to hear the words "extremely hard" and "stupid" used to describe the game.I will agree that there were a couple puzzles that were over the top. The word "coins" comes to mind. The other puzzles with the maps seem to be OK by me. I would say that the game is difficult in some areas but on the other hand, some of that programed difficulty is what give the game great replay value.
I hope you get the opportunity to play W7 again and try a different party or use different strategies.
