Möbius

First, let me say that if you like science fiction and IF, than you must play this game. It is so clever and unique with its puzzle style that once you start playing, you will be hooked until you complete it. DON'T USE A WALKTHROUGH. You don't need one. As other reviewers have said, the puzzle is very logical and rewarding to figure out on your own.

My only complaint would be that the game gave away information that I would liked to have figured out. However, some players may find that these bit of insight alleviate frustration and allow them to concentrate on the puzzle at hand.

Highly recommended!

One note: the game cannot be played on the ipod touch with the Frotz app. This will crash the app.
