This... isn't bad. But there's a fair amount of jank going on. I've beaten the first behemoth, and it was a bit of a slog. The promised 'Shadow Of The Colossus in VR' isn't really right. The fight is very, very simplistic, and you barely climb him. The game is terrible at signposting requirements some of the time as well. VR is not the environment you want to be running around like a headless chicken.
Weirdly, this feels more like VR Dark Souls than VR Shadow OTC. Right down to your friendly blacksmith.
7/10 so far.
