   I was curious about how they did the first-person view on the hi-res screen.    
   The answer was somewhat unexpected: they drew it with character glyphs and a   
   few horizontal lines.   
      
   The game was written for the TRS-80 and ported to the Apple II, apparently by   
   someone who was not an expert in either 6502 or Apple II programming.  It   
   gets... interesting... in spots.   
      
   A full disassembly, as well as a complete walkthrough of the game, can be   
   found here:
