@Cirion, it is required that a non-abstract subclass of an abstract class override any methods that have a semi-colon instead of brackets (see the 'run' method in the FullScreenWorld class). You can also go to the following link in the java tutorials: http://docs.oracle.com/javase/tutorial/java/IandI/abstract.html

Apparently, you need to add the following method into the MyWorld class:: public void run() { }

@LittlePillows, log onto the site and then simply run into a zombie. You will then see the buttons along the bottom of the High Scores world.

The only problem I have detected is that the player only moves when a key is pressed. The pac-man should move in the last direction taken until a wall is encountered unless directed to turn at the next junction.
