Finally, a game where the pricing structure is as clever as its mechanics. A Good Snowman is Hard to Build is an adorable puzzle game about a monster trying to make snowmen, from established puzzle-game designer Alan Hazelden, co-creator Benjamin Davis and composer Ryan Roth. It's charming, cute and surprisingly complex, and it's available for $8 right now, though that number will probably change tomorrow. You see, the game's price directly reflects the celsius temperature in London, Hazelden's and Davis' home base, from now through March 10. After such a rough winter for many people, A Good Snowman is Hard to Build offers a cool reason to be thankful for chilly temperatures.
