How do I get the villagers to fish and plant their own food? Foodis almost gone and they don't have any other way to survive. Also how do I get the rocks removed from the creek?

Hi Drua, Virtual Villagers Origins plays the same as Virtual Villagers-A New Home (the same puzzles have to be solved, etc.). You will find hints and spoilers in the Virtual Villagers 1: A New Home Guide. The Strategy and Puzzle Guide gives you hints whereas the Detailed Puzzle Solutions tells you exactly how to solve each puzzle. It's up to you to choose how much you want to know.

The iOS version differs in that it has new features as described here.
