Tips from David Crane, designer of Pitfall!
"As you set off on your first adventure with Harry, you'll notice two important features: The logs always roll from right to left, and the 'replacement' Harrys (after Harry loses a life) drop from trees on the left side of the screen. So, to minimize the number of rolling logs to be jumped, and the catastopic hazards to be re-tried, simply run to the left."
"Pitfall Harry's trip must be made through a maze of surface and underground passages through the jungle. To capture all 32 treasures in under twenty minutes, Harry will have to use some of the underground passages. I'd suggest that you make a map of the terrain each time you play. Knowing the jungle and planning the best route to all the treasures is the only way to insure success time after time."
"Until you get really skilled at making Harry jump from coc to croc, you might wait until the crocodiles jaws are closed, jump to the top of the first croc's head, then wait for the jaws to open and close again before jumping to the next one. Soon, you'll be skipping across crocs like they were stepping stones in a stream."
"If you find any writing materials deep in the jungle, drop me a line. I'd love to hear how you and Harry are getting along."
