Press the left and right arrow keys to switch between what you want to draw. Press "space" for pen down and "u" for pen up. When you are done, press "D" to hide the image and show your drawing. The buttons in the lower left corner zoom in and out. Your drawing will not zoom in or out with the image behind it. I plan to make more of these, with different themes! :)
