This was probably the first game I really loved and played to obsession (on an Apple ][) It was also where I discovered my first 'wall hack'. The apple version only loaded the current tile into memory - every time you stepped off screen, it would load the new tile from a floppy and reset your character position to the opposite edge (e.g. walk off the right edge, load the tile to the right and reset your character to the left side at the same height). I found out (largely by accident, initially) that if you removed the floppy, it would try to read a couple times, and then give up. It would still reset your character position to the other side of the screen but not update the actual tile graphics & platform locations. You could use this to cheat past otherwise impassible barriers - find a tile you could walk all the way from one edge of to the other at the same height as the barrier, take out the floppy, walk across the tile the right number of times so you are in the tile 'past' the barrier, then put the floppy back in and walk back so you're now on the other side. :) The version I played also had a charming bug(?) where if you underflowed a stat counter (e.g. by doing a 5 manna action when you only had 4 manna left) the game would print the message "I have nothing more to give" and then lock up, leaving it ambiguous whether it was your character that had nothing more to give, or the actual game.
