For now, 2D Boy answered some burning questions from fans, explaining what's going on with iPhone/iPod Touch versions. "There's a lot of iGoo to pour in, and we don't want to release something if it doesn't run absolutely buttery smooth." They also detailed the iPad version's multiplayer, which "you can play two handed, with friends, an animal, anything up to eleven fleshy things touching the screen", and confirmed that, yes, you can totally wear a Goo Ball on your head while playing the forthcoming game.
Oh, right, and 2D Boy also says that a sequel to World of Goo would be "something we would enjoy working on," but it would have to "feel like a perfect and appropriate continuation of the first game." Whether it would be made for the WogPad or not, we can't say.
