This is super neat! Well done, and super relatable! I really liked the *SPOILER* big payoff moment when you rise above the structure and see all the rooms from above. Not sure if it's just my machine, but the mouse sensitivity is VERY high. I understand that part of the core conceit is that it is difficult to navigate the space, but I found myself a bit frustrated when I would lose myself in a void of black just because my hand slipped a bit. I would suggest tuning it down a tad.
