Graviteor

Protect the earth from hordes of unrelenting meteors driven by earth's own gravity. With the flick of a thumb, be the guardian that stands between destructive force of falling meteors and our earth. Play only with a single thumb anywhere you are, whether riding a bus or traveling on the subway. No need to turn the phone, just play in portrait mode, the way you normally use it. Play in short bursts or whenever you are in for the long haul.
