Dune Rider is a freemium (as well as ad-supported) stunt-driving game that starts you out with just one vehicle, one level ("Zone 1"), and a clumsy steering interface.
Not only do you start the game with limited choices, but you're also strongly encouraged each time to buy more fuel, nitro boosts, and bonus multipliers in order to have any hope of getting the kind of score you need to earn coins, which you must then use to buy more fuel, nitro boosts, and bonus multipliers. Hopefully, you can save enough coins over time to buy new cars and zones--but sadly, earning coins is extremely slow (in large part due to the inadequate performance of your starting vehicle), and an initial stash of coins is small consolation. You steer, accelerate, and brake with a row of buttons on the bottom of the screen, and you can swipe the screen while in midair to perform stunts. It's hard to know whether the controls are clunky by design, or just because you haven't made enough in-app purchases yet.
Given the long list of great (and even cheap) iOS stunt-driving games, Dune Rider doesn't have much new to offer. Still, its basics show some promise. Some serious tweaking of the spreadsheets driving Dune Rider's in-game economy could go a long way toward improving gameplay.
