Hi!
Thanks for the feedback. As this is just a "One Man Only" project, I can't find the time between work and family to update it with that. I'm with you: free locomotion is not the ideal.
About having some fixed spots... I did that just for the FOV test. Remember that you can move outside any fixed point because the VR outside movement (you can walk in real life, literally), so the only way I found really useful was to freeze you and the headset. But that is soooo uncomfortable that I don't want to do it for the the rest of the tests. I placed a "shadow" point at your feet for location purposes.
