To access colors, press the pallet button (The one with the brown background and colors). To minimize the pallet, press the pallet button with the X on it. To access settings, press the gear button. In settings, you will find the brush size (which also controls the eraser size), the Start Judging button, which starts rating your drawing, and the See Rating Button, which shows what the computer thinks of your drawing (from 1 to 10). Your rating will be shown in the top left corner. You can resume rating again by pressing the Start Judging button. There are no undo buttons (yet). If you want to restart your drawing, you can press the Clear button.
