I love the idea of the boat making so the could get out of the island if they want to....
also I would like a bonus puzzle..or a hidden puzzle or something...that is not on the list, and it only appears after you solved the ones listed...this could be someting to look forward to..and as the events, this could be random too..you can make 2 or 3 so you don`t know which one are u going to get.
ohh and more than an activity is like fisical change..I think it would really help if you can make thei hair turn gray when they become elders, so we can identify them without having to check the details...

looking forward VV2!!!
