With only a few competitive friends on your Facebook feed you're guaranteed a whole lot of fun from Mad Skills BMX; even without them you'll be hard pressed to beat the AI and unlock the game's secrets.
Very few things to complain about. We miss an actual multiplayer mode, or a full Game Center compatibility, but apart from that, it's entertaining, cheap and a universal app. We really think you'll love its offer, so it is definitely worth trying.
Learning curve aside, it's one of the most competent competitive racers available on the App Store, and the multiplayer and ghost-racing components will give you considerably more value for money than the majority of the competition will.
