Tbh, I've had only 24 hours, so it's definitely over ambitious, and it's pretty sad, that I couldn't use 1st half of the jam time to create more responsive and player friendly game, with more thought rules, but it's a larger project after the jam.
So as extension to tutorial, to create Lumberjack you have to place village near two Forest cells, which consumes the forest cells so you have to prepare more Forest cells around so that the forest will keep on growing around, and allow Lumberjack to collect it. Also, when village has 4 other villages around, it turns into City.
In the end, there is not that much to it, but I'm thankful that you tried it out and left an insightful comment :3
