BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.

Pitfall is not the worst Atari game by any means, but it's nowhere near the best either. The biggest problem is that it's just so dang difficult! I took the left path and holes kept opening up and killing me. I took the right path and at least I made it through a few screens going that way.
I had the NES version of this game as a kid and it's likewise as confusing and difficult.
But props for being unique and not just another in a long line of shooters.
