Hello,
I understand the issue. In fact, we had an export problem related to GODOT, so this version is not the finished one. However, you can still experience the gameplay.
You likely faced the classic problem of resource scarcity. The game starts with one unit of food and one unit of iron. To obtain more, you need to click on the tiles with water or iron deposits. Keep an eye on the resources at the top right.
Thank you for taking the time to test and comment on the game.
