World of Goo on sale for 'your' price; iPhone port comingby David Hinkle { Oct 13th 2009 at 4:30PM } PC iPhoneMy my, how time flies. On this date one year ago, World of Goo entered our lives and, well ... it made everything all gooey. (The good, warm kinda gooey.) To celebrate the game's birthday, 2D Boy is offering the title for -- wait for it -- whatever price you want to pay.Seriously, once you enter a price into the appropriate checkout field, you buy the game for that amount. We'd encourage you to cough up as much as you can spare though, because 2D Boy totally deserves your money. The sale ends Monday, October 19, so start digging under those couch cushions.You may also want to set aside some loose change for the upcoming World of Goo iPhone port. 2D Boy has a build running on a 3GS right now and is working to get the game going on the vanilla 3G. We'll be sure to keep you posted on its progress.
The site's been down for me for the last few hours.
The sale has been extended until the 25th.Also they have released the stats of how many people bought so far, and what they paid. Nearly 17,000 people paid one cent.
