This is a slightly modified version of the original rogue. Centaurs, Rattlesnakes saping your strength, Aquadors killing your armor, Medusas confusing you, Griffins pounding you, Dragons - run for your life. Get the Amulet on level 25 and try to make it back out. Impossible (well nearly impossible) to win, fun to keep trying. Excellent game.
Sorry, no solutions yet :(
