Neat game, I encountered a bug though.
At the very beginning, after I finished the starting dialogue with the party members, if I enter the kitchen (which I should), but leave again without talking to Anna, I re-enter the living room with a black screen. It seems I can still walk around and interact with the people, the text bobbles are showing whenever needed, but the rest stays black. Even if I navigate my way back into the kitchen. I had to reload the site and start over (which isn't bad of course, since it was the beginning anyway), but the bug reoccured when I tried to redo it. I had to refresh the page again and talk to Anna for the black screen to not show up again. It didn't happen again for the rest of the demo.
It's not that much of a bad bug, since it doesn't stop me from playing the game the way it should be played, but it could leave a bad first impression for people who like looking around a lot and testing things out (like me) :P
