Press the arrow keys to move the orange ball through the maze to reach the black rectangle goal.
I added some more detail to the instructions and changed the goal script to display a congratulations screen when you win. Mia used the "add comment" feature in her script for the ball sprite to mark the part of the script that works as a reminder of what a particular section of the script does ("When the ball touches this color it bounces back." To add a comment, right cllick (or control+click on a Mac) and choose "add comment."
