How to finish Third & Second Map. I'm stuck.
The second and third map are very different from the first. The first is open, with many ways to finish it. The others are more puzzle like.
For the second, you have to very much optimize how much food you get out of these bushes, so you can survive the treck across the desert. It is very tight.
The third one, you probably know you need a certain amount of ore to reach the portal. Getting that ore before the world crumbles is the difficult thing. There are a few ways to do it - just one hint: your wagons can also work tiles while being on a bridge.
The first world is the proper content though, so you haven't missed anything. The others are more like a gimmick.
