Dark Castle is an adventure style game, but with low res graphics and some realtime elements (like monsters walking towards you if you just stand there). Based a fair bit on Dungeons and Dragons, the controls are actually fairly simple (all keyboard), and you are on quest to recover a stolen gem from an evil wizard. Since the game is visual for rooms that you are in, you have to maintain your lantern with oil, otherwise all you see is "IT'S DARK", and monsters can sneak up on you. You also have ranged and close up weapons, so that you can strategically assault monsters from a distance.
Dark Castle was one of the winners in Rainbow magazines 2nd Adventure contest.
