I first saw Osmos last year at the IndieCade festival in Culver City, California, and a few months back, (creators) Hemisphere Games shared the news that they were bringing the excellent art title to Apple's platforms. Now, Osmos for iPad has been released on the App Store, and it's just as beautiful and entrancing as the original indie game. The idea is that you control a kind of planet/blob thing by floating around a space-field; your goal is to "eat" the orbs that are smaller than you are by touching them. The challenge, however, is that the more you move, the smaller you get, so the goal becomes to navigate without becoming smaller than the orbs you need to eat.
That may sound confusing, but the extremely ambient game is anything but. Excellently detailed graphics, a great electronic soundtrack, and intelligently considered controls make for a really intoxicating experience. I can tell you firsthand, especially since I heard from Hemisphere a few times during the development of this one, that a lot of thought has been put into this title and how to best implement it on the App Store.
The game is US $4.99, but for the excellent experience you'll get from it on the iPad, it's more than worth the price. If you're looking for a great, original gaming experience on Apple's magical tablet, Osmos is it.
