worldofgoologoDeveloper 2D Boy, the maker of very popular puzzle game World of Goo, has slashed the prices on both the Mac and iOS versions in honor of 2D Boy's fifth anniversary.

World of Goo, which was named by our sister site TouchArcade as the iPad Game of the Year in 2010, is an immensely entertaining game and prices for the Mac version were cut from $9.99 to $1.99 and the Universal iOS version going from $4.99 to $0.99. The discounts will be in place through the weekend.

From the TouchArcade review:

At first, World of Goo is about manufacturing bridges and towers with the stretched tissue of little balls of goo. The point is to provide a path that other goo balls can follow into a metal pipe, the end point. Physics play a key role in this process: you'll need to build sound structures, which sounds easier than it is. Goo isn't concrete.

Each level requires a set number of goo balls to reach the pipe, and each goo ball you use for a structure counts against the total provided. This constant negotiation of goo resources is pleasing because it forces you to think around the obvious solution, which is often one of brute building.

The universal iPhone/iPad universal version is $0.99 on the App Store, down from $4.99. The Mac version is available for $1.99 down from $9.99 on the Mac App Store.

Really? I think the iphone 5 case post is a bit more important than this nonsense.

Seriously, there have been SO many stories about cases that are for a iPhone 4S/5 that it's just too boring now. Apple will reveal what they reveal next week. Just put up with that.
