The visuals are VERY good! The lighting too. But I dont really see how much it is related to the theme (yes ghost are going after you but still). Special object implementation is nice but I would welcome the option to turn off/on the glasses/phone because walking with it was very unpleseant as it was moving up and down. Also, it would be great (and we were also thinking about it when we were making our game) if you would see the ghost only through your phone and not without it. It would push user to use it more and to be more careful. Music was also good, it really sets up the atmosphere that something scary is coming.
Nice job!
