This game is great, but it has some major flaws and definitely needs some improvements.
So what you do, is you basically get essences. These essences help you build things, by either placing it on the object, or painting with it. For example, if you had an apple essence, you could paint one block with an apple pattern, or set an apple itself on the object. Now you can get these essences one of three ways:
Being nice/mean to people
Shaking it from a tree
Prospecting, using a metal detector type thing to find them and dig them up.
So once you do enough tasks for your neighbors, you get your star rating to go up. By doing that, you can move more people in, and unlock new places, like the desert, and the forest. Each person has a set star level for them to appear in the inn, which is where you have to ask them to move in, and build them a house.
So it all goes in a cycle:
Find essences
Build furniture
get star rating up
move people in
repeat
After a while, it starts to get monotonous, which is why i give this game a 7/10
