I find it fascinating that it turns into a "descent like" (6dof fps) when using the ability to "peek" the 4th dimension.
The perspective shifts so that the up-down direction becomes the hidden dimension. So the ceiling and floor disappear (and you have trouble avoiding lava) and you only see the walls of the space.
