As someone who has spent more time than I'd care to admit playing both the first JellyCar [Free] and JellyCar 2 [99¢], I've been having an absolute blast with Chalkboard Stunts [99¢ / Free]. Featuring similar gameplay to the JellyCar series, developer Manta Research ups the ante by including a full featured level editor that not only allows you to create your own levels, but also upload them and download levels made by other players.
The object of the game is simple, you drive your little car across a track drawn out on a chalkboard to reach the finish flag. Buttons on each side of the screen control your movement and the rotation of your car for landing properly off jumps. You can also make your car bounce by tapping the screen. The included maps start out extremely easy, and slowly introduce more gameplay elements such as loops, ramps, and objects you can ram or otherwise interact with using your car.
Much like the JellyCar games, it doesn't take long for these courses to get amazingly difficult and you experience the same sense of satisfaction when you finally beat a level with your car spinning out of control and just barely crossing the finish flag. The levels you can download online vary in quality, but I've had a good time playing through the ones I've tried.
These silly physics puzzle racing games are among my favorite kind of iPhone games, and I've been having a great time exploring the various user submitted levels in Chalkboard Stunts. So much so that this review was delayed by nearly a week because every time I'd sit down planning to write something about it I'd fire up the game and lose an hour to it.
I still prefer the original JellyCar (Mostly because of the awesome music) but if the community generated content in Chalkboard Stunts keeps up, I can easily see it living a long and happy life on my iPhone.
