"Pitfall! is a video game released by Activision for the Atari 2600 in 1982. It is one of the best selling games ever made for the Atari 2600, with over 4 million copies sold.
The player must maneuver a character known as Harry through a maze-like jungle in an attempt to recover 32 treasures in a 20 minute period. Over the course of these 20 minutes, Pitfall Harry would have to tackle dense forests, snakes, bats and insects.
Along the way, he must negotiate numerous hazards, including tar pits, quicksand, water holes, rolling logs, rattlesnakes, scorpions, walls, fire, bats, and crocodiles. Harry may jump over or otherwise avoid these obstacles by timing his climbing, running and ducking, and in certain places he can swing on a vine to avoid them.
Pitfall! was designed and programmed by David Crane."
