Nice idea :-). My only suggestion is that it could have been slightly better if i had to use the cursor keys for something else than changing my course (calibrating stuff or whatever :-P) and see me falling in the background from first person.
Actually that might be a nice idea for a mini game in Occulus Rift - feel like falling from a skyscraper and try to hack your conscience with using the computer in your HUD/glasses :-P
