Nice graphics, sound, and gameplay.  However, after beating all 25 levels in a single sitting, I was a little bit let down.  The puzzles start out strong, but strangely they get easier as the game goes on.  By the time the end credits popped up, I felt as if I had played an unfinished game.  I really like John Hancock's YouTube videos, but I really can't give this game anything more than an average *** score.
