[1] The game was published in 1982 for the Apple II, followed by conversions to the Atari 8-bit computers and Commodore 64.
The game tasks the player with a quest to defeat a magical vampire with the assistance of Princess Sabrina (who is now a fledgling magician) and the heir to the throne, Prince Erik.
It used VGA graphics (PC version), more complex puzzles and a larger vocabulary.
The game also had some digital voice and many of the puzzles involved references to ancient mythology.
