When the green flag is clicked, the cat walks around the edge of the screen. Can you change this to make the cat walk around the edge of the screen in the other direction when you press the space bar? It's not as easy as you may think! Hint: You need to add a script that begins with the block "when space key pressed" from the Control section. You need to add a variable for the direction, forward or backwards, and you need to copy and modify new versions of the Cat's costumes to use when it is going backwards.
