It's the first time the intriguing game has been showed off live as its public debut at E3 earlier this year was in the form of a pre-recorded video of someone interacting with Milo, the teenage boy who is the game's main character.
While the latest footage sheds a little more light on the project, details on the ins and outs of the game are still few and far between.
Not that this has stopped debate about Milo & Kate's merits online. Some see a game where you play with a virtual teenager as creepy, others as a refreshingly different idea.
What's your take: unappealing or interesting?
