Red car: WASD Blue car: arrow keys Desert rally is a two player game. avoid sand and boulders. collect gems. shove other driver off the road. the 'pew' sound means you've got less than ten seconds. OBEY THE JUDGE! I recommend staying at the bottom of the screen so you can see boulders and gems coming at you so you can dodge and collect in time.
thanks to @turtlebunnysky for the Qibli sprite, and thanks to a book for the original game glacier race.
