Riding VirZOOM is a lot like riding a bicycle, there can be initial fear that goes away once it "clicks" for you.
Our motion tech addresses the root cause of simulation sickness for most people (see https://virzoom.com/blog/vr-that-moves-you/), but VR can also provoke vertigo and fear of doing unsafe things that require acclimation to address. For such cases we recommended starting people on slow flat game such as Thunderbowl, which we label "comfortable" in VZfit Play, for hours or days before trying "moderate" or "intense" games that require more turning, hills, and flying. In VZfit Explorer I would start them on long roads with less distortion such as "Route 128, Colorado". Putting them in experiences with more movement or consequences before they feel totally in control can result in panic, which we recognize differently from motion sickness.
It's hard to put into numbers, but from hundreds of playtests we found 10 times more people can play VR games comfortably using our tech than without it. But if you don't start people out in safe experiences like above, maybe 1 in 3 will report initial discomfort. Our safest-feeling game is actually Lotus Pond, but it hasn't yet been ported to VZfit for performance issues.
Regarding Explorer depth effect, what you describe sounds like our Monoscopic option. You're playing on a Quest so can turn it off from the Options menu. Note that it's turned on automatically for Comfort Mode, but not turned off automatically, so you could have enabled it trying that.
