Not a bad free application, good way to burn a few minutes. There are a few problems however; the cars seem to handle as if they are driving on ice, as they drift all over the track on every turn. The engine noise sound effect needs an overhaul, as it is incredibly annoying at its highest speed. Also, the starting track should not have obstacles and odd square turns, it is difficult enough learning the touch controls, I would prefer a simple oval to drift around while first learning the game.
The graphical interface of the game also comes across as a little rushed, but overall a cool game that just needs a few tweaks.
