[PC][More than 10 years ago] A game about jumping to the different rooms and collecting/stealing items

I remember playing it with my dad when i was small. Its a 2D game, probably no pixel style, in gray/dark/dirty colours. We play as small gray creature(i guess) and jump through vents/holes in the walls to get to the different rooms, which are usually dirty and seems like haven't been cleaned for ages. In those rooms live another creatures or animals, we can go unfer their beds and explore their rooms. If i remember right they dont attack, but might say something after you steal something bc they get mad. Can steal socks and other things. I saw this game on YouTube shorts few years ago, but forgot to save the name of it
