The Swatstop will give you the instructions. In this case that he doesn't: The Purple car has W(up) A(left) S(down) D(right) controls The Orange car has up arrow, down arrow, left arrow, and right arrow controls. The object of the game is not to finish first but to collect the most pipises possible. If you touch the hazards or the side of the road you will have to restart at the bottom of the road. You can knock the other player off the road.
Thanks to @benanim for giving me ideas for the color of the road. Thanks to @sussymons for providing me with the Swatstop picture and the pipis picture. Thanks to @a_mailbox for helping me with the hazards. Thanks to a source for the scrolling road. Thanks to @benanim for the purple car benulee picture. Thanks to @687e5 and @adian510 for the whopper picture on the orange car player
