It's an indie city building game that isn't quite as complex as SimCity, but just as hard (or even more!). You start with a few families that have been exiled from their homeland and must make a new thriving city on a new and unexplored land. You will have to take care of the basics of the genre: give them houses, collect resources, make sure they have food, entertainment, health, keep on growing by building better buildings, etc. It's pretty straightforward but that doesn't mean it's easy, once your villagers start dying because you aren't giving them enough food or winter has been harsh it's pretty difficult to come back.
I've been playing it for a few hours now and having a blast with it. Totally worth the price tag in my opinion. If you like city building games I would really recommend supporting this developer.
