World of Goo. Some of you may be familiar with the game since it appeared on the Nintendo Wii a while ago. It's a really popular physics-based puzzle game with nice artwork and design. If you like puzzlers, especially with physics and building schemes, definitely check it out. I should note that it's 40% off until December 5th ($2.99). There's a demo you can try in the Market, too.
