When I was a kid I played a game called Lone Wolf - The Mirror of Death.

You are a knight of sorts and you keep going up this nightmarish tower (fantastic use of PC speaker for sound, btw!). Every once in a while you will duel what appears to be a dark version of yourself. I never made it to the top of this tower, maybe because my parents enforced limits on game time, maybe because the game was just too hard in the end.

Did anyone beat this game? What is at the top of the tower?
