My Review is...
I really do like the game but you could add and improve. The first thing is that an undo button would do good for me. Maybe not for the rest of the people but I like to think that just a simple mistake can be undone with a button. Anyway...the other thing would have to be a bit more difficulty. Being able to choose a New Puzzle and solve that one instead of the one you are currently on is opting out and makes it less interesting to solve a hard puzzle when you can just as easily press a button and make it an easier one. However, besides these two things (and perhaps some more revisions in teh future like different music throughout the game and perhaps locks on some stones to not move them or something for challenge sake) it seems like a basic game.
