Really neat! I think from a balancing perspective, there isn't quite enough time to freeze the ghost before he gets you. He'd show up in my light space without much time to press left shift. If I wasn't super fast, it would get me. I know sometimes the ghost would sound, but it wasn't always consistent. I think just a tiny bit more time would've worked. I agree with some of the other people here that the ambient of the night time was really good.
