I'll try to answer that later, since I can't remember now.

To make this clear, a different seed doesn't change the mazes, it only changes the starting point. To change the mazes, you have to change some of the generation rules. This is basically possible by changing some constants, but for more, you'll have to change some code.

My above explanations reduce this to the choose of starting point. But I think, before this, it took him more work to choose the best bits form the LFSR and to balance the game.

Sure, use the code from Pitfall! :-)
Have fun!
