Demon Stalkers

Demon Stalkers is essentially a Gauntlet clone. You must travel through 99 mazes, before meeting the final demon. The game features different enemies as you progress through the mazes, with clues to progression built-in. There's a 2-player co-operative mode. The in-built level editor uses pull-down menus and offers a high level of flexibility. As well as creating actual levels, you can create an integrated storyline and game world, as the text on scrolls can be edited. (mobygames.com)
