Pitfall was originally released in 1982 for the Atari 2600 console. It was designed and programmed by David Crane, who was a developer at Activision at the time. Pitfall is considered to be one of the most influential games of the early video game era, and it helped to establish the platformer genre. It was also ported to numerous other platforms, including the Commodore 64, Apple II, and Atari 5200.
Asked on the Stardot forums if he is working on Pitfall 2 next, Lindsley replied, “I’m all Pitfalled out, I might do another Atari conversion at some point in the future though”
