Pyst shows us what the island of Myst would look like after 4 million people (players) walked over it. The island is full of litter, most buildings are ruined, and graffiti reveals secret doors and solutions that players have to find themselves in Myst. Pyst's gameplay consists of a series of interactive postcards with no real puzzles to solve; the player advances to the next card at will. The game features both three-dimensional graphics and animated drawings.
A demo of a sequel titled "Driven" (a reference to the Myst sequel Riven) appeared on CD-ROMs of later Parroty Interactive games. Though graphically more advanced than "Pyst" (and allowing some movement), the game was apparently never completed.
