I really like the looks and feel of the game. It looks good and quite polished. I would love to see a proper narrative in this. 

Though one thing I noticed is that with just binary option, most decisions would seem a bit obvious. Like opening up = good, closing = bad. So just a thought I had was that from a gameplay perspective you could add some sort of "comfort" bar, that fills up once you open up with some things. And if something is okay for you to say, is in your comfort - your comfort level rises, but if you share something too deep, or you get a negative response from the other person - it goes down. That would give more dynamics to the game, making it more tricky, just like real conversations are sometimes :)
