Interesting idea. It fit the theme quite well but I felt there was some inconsistency in what the player can safely pass and what are hazards that will cause an instant fail and restart.
A few times I was cruising down a hallway only to run into a message be bailed back to the start screen before I even had a chance to read it, so I had to go back a few times, which felt a bit unfair.
The music was simple, but I felt it fit ok.
