I released Orbalus, my first iOS game in the AppStore yesterday.
Based on the Unity engine, the basic gameplay is as simple as it can get, being wrapped in graphics as good-looking as they can currently get for a game like this on a phone. The aim of the game is to collect different kinds of Orbs. These Orbs can not be controlled directly, but only by manipulating other orbs in their proximity.
Get it from the AppStore now for your iPhone or iPod touch with iOS 4.3 or above 🙂
