OK so I m getting a NullPointerException on line 277 -- weird...

What I am trying to do is if the mouse is inside the coordinates and is CLICKED to focus back on the game jpanel...

line 277: game.requestFocusInWindow(); // request focus in game JPanel

Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException

should be:

      public JPanel game = new JPanel();

>                   JPanel game = new JPanel(); // game panel

and delete that line
