Okay, "highScore" there should be "highScoreDisplay".

Yes. Now, remove the ", false" from line 14 and add the 3rd constructor given previously.

Is this the previous constructor your referring to and do I use this to replace lines 11-14? 
public MyWorld(int w, int h, int c, boolean b)
{
    super(w, h, c, b);
}

Yes -- referring to that. No -- not to replace; but, to add in addition to.

You probably still have not created an Actor subclass called SimpleActor.
