The car itself is kinda ugly and simplistic, but check out the spring rockets! I found out how to turn them on and off. Arrow keys to drive with up to fly. Can control itself side-to-side while flying. Also take a look at the muscle-like objects used to power the rockets.

Course has lots of choices for direction and has many optional obstacles. I built it to accomodate various kinds of exotic vehicles.

NOTE: These don`t always work and I still haven`t figured out how to influence their reliability, so you may need to restart a few times before all three rockets work properly.
