Definitely nauseating, I'm glad it only has three levels so far lol. The idea is great though, I wonder if it could help if the player didn't spin with it, and most importantly always stayed centered. Having the camera be more smooth is a ncie feature for many games, but in this case I think it was more disorienting and gives your eyes no place to focus, because the actual center point always moves around the place depending on orientation AND momentum. I also wonder if making the world start rotating slower and speed up would help ease the brain into it
