Really interesting game. I love the atmosphere, may I suggest adding some random vocal lines every now and again that give a "What if they're talking about me?" feel. For an extra challenge, and to utilise your look mechanic more, may I suggest needing to look at what you need to pick up in order to do so? Or perhaps needing to look to see where people are before you get too close. At the moment it feels as though I'm just avoiding eye contact and can see everywhere regardless of which direction I'm facing. Overall you've nailed the feel of what you're going for, and the game over animation is very good - made me feel uneasy!
