I don't know for sure if I have finished the game or not so I thought I'd ask you. I have all of the puzzles finished anf all the possible tech upgrades. Does that mean I'm done? Beccasue I haven't figured out anything about the thing that was living in the cave before I moved the rock or the weird face that took one of my villagers (I'm assuming it's the same thing). Is there going to be a second virtual villagers game?

There has been a lot of good discussion about that topic in the forums. Here are links to some of the threads:
