We've written about how cool World of Goo is previously and if you haven't tried out this innovative and more importantly fun game from developer 2D Boy, you are really missing out. This week marks the game's first anniversary and to celebrate the dev team have a unique promotional offer.

From now until October 19, you can download and purchase the PC, Mac and Linux versions of the game from their site for any price you want. Yep, that's correct. You can pay as little as one cent or as much as $1 million; it's all up to you. We suspect that 2D Boy would like to have people pay as close to its normal $20 price tag as possible but hey, whatever floats your boat. It's all up to you.
