have a few ideas
what about expanding the grave yard
or have list of peoples that have past away
what about once the cave is open let some one with master skills explore it or maybe they have to invent fire or buy with teck points so they can see inside
or maybe once you done that have the cave to come out on another part of the island and find differint food and be able to start another tribe there
and what about founding the school it does not have no purpose what about when the kids do go to school give them maybe 1/100th of teck points each time
just having some ideas have more but page aint big enough
but keep up the good work iam a plumber what do i know
