Cass25 is right. Turns out all that is a teaser for VV2. The new game is 75% completed. Everyone had complained that the ending was not satisfactory. Once the cave was revealed, we all thought our villagers would find a way to another part of the island. We just did not realize beforehand that we would have to wait for part 2. Perhaps the eyes peering over the top of the boulder belonged to someone from the other side, a native of that island, who was wondering who the villagers were and where they came from. Turns out the game is to be a series. I don't know how many games are to be in the series but I guess that largely depends on how the other games sell.
