I did it!!!! I escaped. Don't know if it was the updated version. I downloaded it on Dec 23rd. It took me several attempts and I had to learn to stop freaking out when I hear the hugger on wheels. I learned to loose it after you said how. Sometimes it seemed a bit too smart not following me, but cutting corners and intercepting me. It was brutal especially if I had 3 keys collected. I must admit, the architecture and atmosphere is what was bringing me back. Amazing game!
