Armadillo Run is definitely a great game. I wish I could say the same about the article.
I can't help but wonder how in 5 pages of text, neither the developer nor the writer saw fit to point out that AR is a much-improved revisit/remake of the quite popular and famous Bridge Builder http://www.bridgebuilder-game.com/ , which amongst other things won the audience award at IGF2003. It's had several sequels, including the 100% free, minimal "Bridge Building Game" from the original author: http://crypticsea.com/
While AR certainly made vast improvements to both the interface/useability, range of building materials, aesthetic, etc. the article seems to suggest that the game idea itself is original, when it's quite simply not. BB features all of the basic mechanics found in AR, the similarities are far too striking to be accidental, and frankly it saddens me when such a great, literate magazine fails to do at least a cursory amount of research before heralding a game as a great innovation. A great game it may be, but it is a game whose greatness lies it its refinement, improvement, and advancement of a concept introduced by others. The choice of introductory quote was much more apt than perhaps intended.
Not to mention, both games owe a debt to the various "The Incredible Machine" games, as a previous poster mentioned.
If you were writing an article introducing Duke Nukem 3D, it would be irresponsible if you failed to mention Wolfenstein or Doom, wouldn't it? And yet this is exactly what you've done by omitting any reference to TIM or BB, respectively.
