great start
Awesome concept, you have to be quick, think on the fly, action oriented.
Allows for you to pull of tricks you think look cool, or ride in your own style, trying for speed or style. Sometimes even allowing for you to chose your own path to the end.
Very tricky, looking back and forth between the map and the field for how to go about the race, but one doesn't distract or require more focus then the other.
I believe this was a cool entry to start with, and could definitely be built upon. More features would be cool. I was thinking of having tracks that actually moved, so you really would have to switch on the fly, but couldn't possibly depend on the same tactics every time you race the same course. Colors moving back and forth, or in waves.
A story would be cool as well. Maybe even being able to customize the vehicle somewhat.
Was a tad short.
