What Happy Sad Face actually does (from store listing)
Happy Sad Face was originally designed to help parents track their young children's behavior...but then something happened. You asked for a game. Yes, you! My users!
By the request of HSF users, the app has been re-imagined as a clever puzzle game. Some levels are very simple while others are nearly maddening! Can you become a Happy Sad Face master?
