We're glad you like the writing and the atmosphere! We were going for a spooky abandoned laboratory studying things that should not be known, and I'm happy that spooky vibe came across for you.
The puzzles are less about "turning in circles" and more about simply "not looking at something." While you're looking at one of the quantum objects, it's locked to that position only, but the second you look away it will change position. But I can totally understand why they didn't work as well for you. With only this mechanic in a vacuum, it's difficult to make a puzzle that teaches you the mechanics, but that also can't be solved by brute force/spinning the mouse around. It's the sort of problem that can only be solved by a lot of refined level design and playtesting (which you have also helped with!) Funnily enough, I never even thought to walk out of the stair room backwards, I always looked sideways or downwards at the stairs when climbing. So thanks for showing me an alternative way of solving the puzzle!
Not sure what to do about you feeling sick. Maybe it has something to do with the FOV, or the mouse sensitivity? Hard to say for sure, but we'd definitely like to avoid that in the future. First person shooter-style games can be hit-or-miss with some people.
And you can totally make a video featuring our game! We look forward to seeing what you have to say :)
