I have found Inanimate Alice, an interactive story told in 10 episodes. It looks pretty interesting!
This is taken from their site
'Inanimate Alice' tells the story of Alice, a young girl growing up in the first half of the 21st century, and her imaginary digital friend, Brad.
Over ten episodes, each a self contained story, we see Alice grow from an eight year old living with her parents in a remote region of Northern China to a talented mid-twenties animator and designer with the biggest games company in the world.
