If you believe that all games require keeping score, attaining badges, and testing either reflexes or mental acuity, you will rate this a 1/5. Otherwise, it's a hilarious interactive movie; 5/5 from me.
Lots of fun, but I was kinda expecting something to happen when I finished the last puzzle...
Also, would have been nice to display your "best" time, so that you could replay it and try to do better.
