I decide to uninstall it and do not back for a very long time. First - there is no merchant or third island. I manage to find good place for farm and build early there a wall and a tower for protection.
Somehow I manage to build army , 3 knights plus archers, destroy all 3 portal to the cost and build ship.
Either it is bug or some artificial hard chalange. People write there should be winter after few days in game, but I have something different red moon night after another red moon night over and over again till evening is overrun and destroyed by greedy monsters. Why game do that?
When I start playing I feel relaxed, game was too slow, but manageable.

What dogs do? Is rescuing them worth?

What affects monsters? What make them stronger?
