Artifex Mundi is so far ahead of the others in HOG detective game design for iPhone its crazy. They are in a class all by themselves. I said in my other review that the only flaw in the first one in the series was no teleporting map. The sequel has one. I didnt want the game to end. What up with the actual imaginative STORY? We get a bunch of good writing without paying extra? Its brilliant to let the gamer choose matching objects over hidden just for a change. I really enjoy arranging evidence on a board. Sign me up for the third in the series. All other designers, DO THIS. This is how its done.
