At the surface the game seems pretty easy: gaze out into the stars to find our home planet Earth. But there is a deeper story there that starts to get fleshed out as you progress and it makes for an enjoyable and peaceful experience. Only reason its not 5 stars is due to some control issues with the touch screen and not a useful map which can get confusing. The free part of the game got me hooked and ready to buy the full version! So much fun!
