You figure how it works in first few runs. Then it is just the same game loop for all other runs.
The problems is there very little thing to do and there is very little that you can control.

Basically, it is just use the resource on the map to build product to fulfill the missions. There seems to many different types of item but they are similar items with different skin.

The game loop heavily depends on the resource on the map and there are nothing you can do if that resource is not available. You just build whatever the missions needs and win. There is no strategy really involved.
The skill tree does not feel important. Most of them are just changed the stats for a few percentage.
