World of Goo has just been updated with universal support, bringing the lovable blobs of black tar-things to the iPhone and iPod Touch. If you’ve never played the PC or iPad version, be prepared to spend hours building elastic bridges and structures to reach the safety of a Dr. Seuss-like vacuum pump. The game is slightly pricey at $4.99 [iPhone-only version is $.99 for 24 hours], but is worth every penny. If you already own the iPad version, just update through the App Store for extra-mobile playing.
World of Goo HD is now Universal! Buy once, play on any of the following devices: iPad, iPhone 3GS, iPhone 4, iPod Touch 3rd gen, iPod Touch 4th gen.
