1. Click flag each time to restart, 2. Then click "space" and do your drawing, i think the max time you have is 20sec to do your drawing so hurry up. (BTW, you have to press to draw and the crayon will always follow your mouse) 3. Then click "a" clickly after that you've finish your drawing. 4. Then REclick "space" to see your drawing being redrawn!
