First off, nobody likes a cheater, and that is what this game does. If this app is representative, of the integrity of this company, then Id rather proudly own a timex. You play for hours to get upgrades, and in the end? Racing in the unlimited, and jet classes, if your ahead, you get slammed into the ground, slammed into the pylons, all of your control is lost, and in general all of your upgrades, are gone. Of course, this only happens in the final race, so that all of your effort to get to the final race, Was A Complete Waste Of Time!!!!!!!!!!!! To the developers....Stick your pylon up your race.
