If there was a goal I could rate it higher but there is no goal, there are no upgrades, and there isn't a story. As it is now I can only give it 2 stars because it is a fun concept but it is lacking in some key design elements of this sort of game.
It seems to me that this would be a facebook app..... but.... It's okay I guess. To be fair I haven't played much of it yet. My opinion might change later on.
Glad you enjoyed it :
