I wasn't sure if it was just my feeling weird all day or if it was a touch of glitch-caused motion sickness. I get it badly with 1st-person shooters. I bet a few susceptible people will get motion sickness if they do as much quoin hunting as I was doing.
Giving the option of moving through a location via a series of sections instead of a long, fluid single section should fix them. Have initial overlap off the sides of each section to keep a little of the multiplane effect. Maybe keep each section nearly static and scroll to the next part at lightning speed when they move into it.
