When you first come to a new location, you see its entire territory hidden behind clouds. To be able to move within the location, you need to cut out the grass, bushes, stones, and trees that get in your way.
Single clicks on these objects only bring you a modest reward, but if you click one of them several times in a row, you get a bundle or a stone clod, that turns into a heap of gifts once you bring it to your home station.
Many locations have a key building that is found far off in the clouds. You need to find these buildings and complete their construction to later use them as warehouses and exchange platforms.
