Use the arrow keys to move the unicorn. Click on the evil creatures to change them into good creatures. When you get to the end of the screen, if nothing happens, click space.
It was working before, when the unicorn reached sprite 1, a green bar that matches the bushes, it changed the background to sparkling. Then, it glitched and stopped working after that. I changed the unicorn's hooves, because white horses have tan hooves, not gray. Only black horses have gray/black hooves.
