Fun game, but its impossible to win any race with the bike you start with. You have enough credits to buy a second bike after a few races, but even that one isnt nearly fast enough. Earning credits to get the next bike will take forever, since it costs about 59,000, and I can only earn 100-200 credits per race. Contrary to what other reviews say, there are IAPs, I can pay an IAP to get credits. I cannot unlock the third track since I cant finish in the top three, therefore if I want to continue, I have no choice but to pay-to-play.
