I have downloaded and tried this. Didn't get very far in before I died.
The 10 minutes I played were chilling, I had the sound way up and it was the dead of night - the game gives you that feeling you get in those dreams where all you want to do is run away but you feel slow and heavy; not sure if that is intended but it certainly adds to the tension. Definitely will go back to this one of the nights! Good stuff
