so, i had been beaten by Mr Ogo and its army. He litteraly killed everyone.
Unfortunately for me, after the army won, it stayed in the town, making impossible for new coming hearthling to do anything. They get killed right away. Is that a desired design ? I suppose not or i would have received a ‘game over’ note.
You can just wait, enemies normally de-spawn after a while (or maybe ogo doesn’t) so yes, they haven’t added a real game-over screen yet, but it is game over.
