It's a good idea to spawn a lumbermill at the beginning of the game. I'll keep it in mind in the future.
Thanks for the feedback :)
Hello, Decalierce)
Unfortunately, the desire to complete the bonus challenge causes a negative gaming experience. I'm sorry.
I should have added a little guide, I guess. Most likely, the problem is that you didn't have enough resources when trying to build. Clicking on the hexagon opens a menu with buildings that we can build and they have their price (current resources are marked on the top left). At the very beginning of the game, we only have enough for the lumberjack's building.
In general, there are two quests in the game, they are marked with a book icon.
