Here are some more screenshots showing the actual About by PCalc interface in action on visionOS. The main controls have virtual joysticks, but there's a list of gestures you can assign to each hand, including a point and teleport option for people who don't enjoy fast movement in VR. Gamepads are fully supported too.
You can also just choose between some points of interest and take in the sights. The settings let you tailor things a bit if you want the controls in a slightly different place.
I should have probably mentioned that it's free. I'm as bad at marketing, as I am at charging for stuff.
