I broke the game :X
Clicked on end turn and an error appeared :D
Oh ok. Well it took me few times to understand how the game works. Probably 10 times I failed at the first turn and the second. After that I noticed that the villagers disappeared after the battle, which I didn't understand why. After 3 times I checked at the tutorial and realized the connection between the weat, villagers and swordsman. So yeah, the tutorial did actually help and I managed to finish the game.
