Drew Davidson, the Director of the ETC walked us through parts of this game showing us how the attention to detail in this physics puzzle game including graphic style, sound effects, and smart, satiric writing all combine to make a great gameplay experience.
The Tower of Goo came out of the Experimental Gameplay Project in which each game must be made in less than 7 days by 1 person, and show off something never seen before. Another game from this project is Crayon Physics.
The World of Goo should be available on Wii Ware and PC on 10.13.08. It is available for pre-order at Amazon.
