Press the green flag! Press the up arrow button to prepare, and press the down arrow button to let the car start moving and space button to let the car turn. Try not to touch the walls or edges! The car will go faster and faster.
This was my friend Juzi Yang's idea back when we were in middle school. We created something similar in real life using remote controlled car and cardboard walls to race our remote controlled cars and I thought it was a really interesting thing to move that idea in scratch!
