I think that villagers should be able to interact with eachother. You can't make them interact, except with children. You should make more options, such as talk, tell joke, give shells. I also think that there should be shells to trade for clothing, tools, etc. in place of tech points. Villagers can earn shells from any succesful tasks. I think there should be animals, famlies/groups of villagers on the island, different foods, different abilities and that's all I can think of now. Oh and relationship points would be great, too!
