I applaud the author's innovation, but I have to take issue with the recent trend of physics-engine-as-gameplay. I'm not sure if I'm too cynical (I can enjoy this game for a while) but I just don't find them fun in general. Phun (no pun intended) isn't really a "game" to me, it's more of a software toy. I think it might be because realistic rigid-body physics are still fairly novel in games, and seeing realistic reactions in-game is inherently satisfying for some reason. I think we'll see a continuing rise in the number of "physics-based ______" formula games, followed by a sharp decline.
