First off: lol it doesn't. It's currently running at 0.4FPS on a Galaxy Note 10. Secondly, raymarching usually involves something different than NURBS, which are Signed Distance Functions (which Inigo,the author, is quite fond of). These have no proper authoring tools to support them. The few games that I know of that uses them are Dreams and Claybook, and that's only as a descriptor of geometry. Dreams then transforms those SDF Into point clouds, then into triangles. And Dreams has basically been the research project of an employee they went through every possible failure before reaching something tolerable.
