I love the atmosphere of this! I think I might just be biased towards towers lol. I love the idea of playing as a safety inspector as well, there's lots of ways you can take this post jam. Like a few others have said, the bobbing did trigger a little bit of motion sickness for me but you could remedy this easily by either switching the stair colliders for a smooth ramp, OR you could separate the camera system from the actual player to do smoothing.
Great work, I hope you continue to develop this!!
