Just draw with your mouse! Press number keys 1-9, 0, a, or b to change the color, and use the up and down arrow keys to change the pen size. Press space to clear. To reset the sprite size, press r. Press z for more backdrops. Click the flag TWICE.
Thanks to @TerribleProgrammer for the idea and the color script. (For some reason finding the colors to use in my script is so hard you have to drag the mouse around.)
