Doesn't Work – Desert Bus Review

I just bought this game for my iPhone 5S and it looks a lot like the original Desert Bus. But when I try to play, I cannot steer at all and it is difficult to start moving. My car simply turns to the right (I know it's supposed to do that) but it is completely unresponsive when I try to tilt my phone to turn left. Please fix!
