Needs to be easier. – Traffic Rider Review

I love it but I’m stuck on mission 15. Also, why do I have to pay for a different color? I love that there are no really long pop up ads, and how you can just ride in the middle of the road and get close overtakes, but missions are way to hard when they say there easy. Please fix the color problem and make bonus levels that you can complete for gold.
Review by rating is hard on Traffic Rider.
