Your fleet steadily grows in number as you take over more planets, and eventually you can amass a fleet of galactic proportions with which you can vanquish your galactic foes. The game involves taking over surrounding planets in a galactic cluster with your fleet of ships-basically, triangles-in order to flush out and overtake enemy commanders.
It's easy to say that there's a faint resemblance to Stardock's excellent Sins of a Solar Empire in Galcon, a mobile real-time galactic strategy game from Imitation Pickles for the iPhone and iPod Touch.
