I've got VR, so I'll give my 2 cents.
I'm using an older Windows MR headset, and I had to map the controllers manually since the dev's haven't done it yet. Not a huge deal, just sort of annoying.
Right now there really isn't anything to do. They have a short tutorial, and then she stands in some poses. They don't have any audio, not even royalty free music.
They're trying to implement a "pelvis control" mechanic, which is super wonky and awkward. One of your hands swaps control to a virtual pelvis and you're supposed to put your controller into your pocket and position it so that when you move your hips the pelvis moves too. That works just about as well as you'd expect.
Definitely wouldn't say this is pushing any boundaries at the moment, VAM does just about everything they're trying to do already.
Not really worth the download at the moment imo.
