Select the Race mode first. Controls: Purple Car - x to turn right ; z to turn left. Red Car - right arrow to turn right ; left arrow to turn left Further Tips: Hit the barrier and you'll bounce (sort of). Drive over the yellow strips for a power boost. If you go off the track onto the green surrounds you'll drift. If you hit the edge of the screen or a brown wall you'll explode. First to cross the finish line (after number of laps you selected) wins. Have Fun.
This project was remixed from an existing Scratch 1.4 project. The existing project (called Racing Car Game) was created by Computing At Schools to accompany their Scratch Guide, which I would recommend.
