Think of Gnog not as a traditional puzzle game, but as a collection of digital toys / complex puzzle boxes. You basically tinker with a bunch of them and use trial and error to make them work. That sounds kinda weird as a game, but it felt as wonderful in the same way as playing with toys as a child. Plus the superb art direction and music really elevated the experience. My only criticism it the short length and that the mouse control could use some tightening in a few places, but those are far from a deal breaker.
