Thanks for playing! You guessed right :} the stairwell is only about 10 flights long, and the game will seamlessly teleport you to the middle of the stairwell once you go far enough down. A variable keeps track of how many "loops" you've done, and that's how the game events happen. The dense fog definitely makes teleporting the player around a lot less noticable. I actually have some screenshots of this on my Twitter if you wanna see more (@inkghst) and feel free to DM me if you have more questions or just wanna talk game dev.
