Completed the game with a score of 500 in one session without even understanding the rules. Too easy to just randomly click your way through. Fantastic game artistically, executed fluidly, but the concept behind the puzzle, while original, is simply too easy. It also feels like it's set up in such a way that it encourages brute-force attempts by not penalizing multiple tries on the same board and allowing you to instantly start over.
I honestly spent at least an hour trying to figure this damn puzzle out.. and the fruit of my labour is this: http://FantasticContraption.com/?designId=1906217 (#19 - Back and Forth)
