Press, tap, or hold the space bar. Right now the space bar will move Tia to the right, and she will wrap around off the right edge and back to the left. She gets caught at the left edge of the screen, however, when she moves to the left. Modify the script so that Tia's face wraps from the left of the screen back to the right, but gets caught at the edge of the screen when moving to the right. Modify the script so that her face jitters up and down while moving instead of rotating.
