The results are in for 2D Boy's World of Goo birthday sale (which featured a "pay what you want" model), and it seems the developer is pleased enough with them they're extending the promotion until Sunday, October 25. Naturally, the site is again now experiencing trouble; we were greeted with this endearing message:

I am too stressed out. Try again in a minute or two. -the Server

Straight off: 57,000 sales were made, with 30 percent of those being for the minimum amount of one cent. For those and all sales under 30 cents, 2D Boy made no money due to PayPal's (fair) policies. The second highest bracket was $1 - 1.99, which accounted for 28 percent of purchasers. In third is the $5 - 5.99 bracket, accounting for 13 percent.

Those figures are depressing, but there are a couple of surprising twists. First, Steam sales (which did not offer the "pay what you want" deal) rose 40%, and WiiWare (same) sales rose 9%. People really like Steam, particularly when it makes more sense to shop elsewhere, apparently.

Second, the amount given increased as time went on:

Lastly, to gain further insight into what went all went down, 2D Boy conducted a survey, the results from which they conclude, "despite there being a lot discussion around what games are worth and the dollar value of an hour of play [...] how much the person feels they can afford seems to play a much larger role in the decision than how much the game is worth."

Somehow, despite these disparaging numbers, the developer seems very pleased with the outcome and encourages others to do the same with their titles. If we ever catch you in a bar 2D Boy, drinks are on us.
