Instruction: The objective of the game is to find the way out of the maze.
   Start: click anywhere on the applet.  
   Control:
      LEFT/RIGHT ARROWS: to move the character left/right
      UP/DOWN ARROWS: to climb up or down (if there is an opening).  
           To climb up, the nerd has to be right in the middle of the opening.
           To climb down, the nerd has to be right the the edge of the opening.
      S : stop (stand) or to toggle turn left/right.
      R: reach a door opener (in the shape of a lion head) to open/close doors .  
          There is a secret door opener (not in the normal shape) that will open the exiting door.  
          The doors are timed to closed and trap the character.
      F: fight.  Can only score if the answer appears on top of the monster is correct (in Math ON mode)
                                      or there is a sign, which you have to figure out (in Math OFF mode).
      Q: generate new question (only in Math ON mode). 

        In Math ON mode, to pass an obstacle or to score a hit on a  monster, you have to wait until the question and answer is correct.
