This is, quite simply, the best puzzle game I've ever played. This is due not only to the puzzles themselves (which strike a wonderful balance of simplicity and challenge), but also to the wonderful world that has been crafted around them. Every corner is considered- every new vista revealing a new marvelous wonder- unpeeling one layer after another. The fact that this experience is consistent all the way through to the end is a sheer testament to the creative will. What more is there left to say, but that upon finishing this masterpiece, one wishes they could play it all over again for the first time.
