Riddle of the Sphinx

Riddle of the Sphinx is a 1982 vertically-scrolling action-adventure game written by Bob Smith for the Atari 2600 and published by Imagic. As the Prince of Egypt, the player must collect treasures and gain strength to rescue the land from a terrible curse. It was Smith's second game after leaving Atari for Imagic, following Star Voyager. Smith wanted to branch out from shoot 'em up games and was inspired by the Rosicrucian Egyptian Museum in San Jose, California. Players collect an inventory of items and manage stats including health and thirst. The second player controller and difficulty and graphical switches are used to interface with these features.
