I am only playing the demo version of Virtual Villagers on my mac, and I am wondering, how many puzzles I can do. Since I can only reach the second level of building and farming, I am not shure if I am able to fulfill any more puzzles. i have solved 6. Can anybody help me? I would really really really like to contimue playing virtual villagers without buying the full version, but there is not really any point if I cannot continue with any puzzles...
