** Apple Design Award winner and iPad Game of the Year! ** Enter the Darwinian world of a galactic mote. To survive, absorb smaller organisms and grow—but beware of larger predators. Osmos features unique physics-based play, stellar graphics, and a hypnotic ambient soundtrack. Absorb or be absorbed! “The ultimate ambient experience” — Gizmodo “Beyond doubt, a work of genius" — GameAndPlayer.net THE CRUX: you must grow by absorbing smaller motes, but to propel yourself you must eject matter behind you, causing you to shrink.
