I love the styling; the problem is that the play isn't really a puzzle: you can move the pieces anywhere by sliding them as far as you want. Once the locks come in, that is just irritating but doesn't add much strategy. Not too much of a challenge. Also, the red and green squares were a bit difficult to distinguish for someone who has trouble with color. It would be better if each tile type had a different shape too, circle, square, and triangle for example.
