line 16 because there is no Scoreboard class and the getScoreboard() method has been removed from the MyWorld class.

You could work on the title screen or build on the game.. Your choice. However, if you have OCD, you might want to have something in the background of MyWorld; so, working on the title screen might be considered next. Add a new method in MyWorld called titleScreen. Then call the method at the end of the main MyWorld constructor. For now, add the following lines into the titleScreen method: 
GreenfootImage img = new GreenfootImage("METEORS", 84, Color.GRAY, new Color(0, 0, 0, 0));
getBackground().drawImage(img, 400-img.getWidth()/2, 40);
