The great experiment is now over for 2D Boy and now that their "any price for World of Goo" sale is officially over the indie developers have revealed some more info about what happened during their unusual sales promotion for their acclaimed puzzle game

During the 13 days of the sale, the company sold 83,147 copies of the game on their web site. Sales of the Windows version accounted for 65 percent of the total sales although oddly enough people who bought the Linux and Mac versions paid on average more than the Windows users. The average donation actually went up after their first news post on the subject. By day 12 people were paying an average of around $3.25 for the game. Finally one person actually paid $150 for World of Goo, over seven times its normal $20 price.
