Definitely. I remember at the beginning Climbey would cause minor confusion if I'd unexpectedly fall, now it doesn't faze me at all.

The downside is that I think I used to be more "immersed" at the beginning. Now while I do still enjoy "being" in the 3D environment, at the same time it seems I am more aware of actually being in my room (which at least protects me from motion sickness and from hitting furniture so often).
