I used to think this was a good game, now I'm not so sure. For one, its really bad when the only way to get credits is by racing or spending actual money. And that brings me to my second point. When you actual do spend your money, the game will say transaction failed because of poor connection even though your connection is fine, and yet Google Play will still process your purchase! So now, your out however many dollars you spent to make the purchase, and yet you have nothing to show for it!!
