To celebrate the 1 year anniversary of the wonderful World of Goo, 2D Boy are letting you pick your price for the game - for one week only.

Until October 19th, you can visit the World of Goo site and pay any amount of cash you want for the gooey puzzler. If you're yet to give it a go, there has never been a better time to grab a piece of the action.

Head over to the WOG site and check it out (Note: at time of posting, the site appears to be getting hammered, hence it's not loading. Be patient!)
