A super well made game, hyper polished and sounds great too!
I think the idea to have only one object per room is great, it means you can't just put 3 of each thing near the exit and you'll be rapidly cleaning up the path ahead while trying not to be spotted.
The tips system is super smart too and I love the little touches like not being able to vent while holding an object. The detection meter is also very generous and the clients move quickly between things you have set up, which help to make the game super playable.
I also love how readable the game it, I always understood what my clients wanted and what each interaction did through appropriate icons.
An excellent submission!
