Brain Cube by Ximad has been updated in a sequel game called Brain Cube Reloaded. The game involves moving a 3D, rectangular object around a map, avoiding objects and making your way to the end of the level. The game, which is being offered for free in App World, has a lot of levels to keep you busy, as well as BBM integration and graphics that are really easy on the eyes. The device support is pretty great with Brain Cube, and supports a wide range of devices from the 8300 to the 9900.
