It has good graphics or as best as you are gonna get for a game like that. You start off with a tribe of people. My tribe has ten people. I don't know if they count the children or not. You should have a job to do and if a member of your tribe does not have no work you should assign a job for them.
Your tribe folks get married and all you have to do is click a bell to find a suitable companion and then the bride or husband will be chosen and they will go to a spot and you pick them up and move them to the spot to get married and then afterward they will have a kid and the kid will grow up eventually and you can assign him a job.
You have to find zodiac keys. Once you find them all I guess the story is done. I just got the game from Bigfish today in the daily deal so I am just getting started.
The game runs when you are not playing the game. Sort of similar to virtual villagers or fish tycoon unless you turn that part of it off and you can turn it off so it don't run when you are not playing the game and you do that when it asks you when you are leaving the game.
