This is a super cute concept for a space-themed game! I agree with the other comments here on the sound design -- when I first pressed 'K' I thought the game was trying to tell me not to do that, haha -- but I definitely prefer a simple music loop to having no sound at all!
I think it would be cool if the game was on a grid so the player was always perfectly aligned with the elements in the room; I had a handful of instances where there was one dirty appliance left but I wasn't lined up with it just right to get the message indicating it was dirty.
Very much a worthwhile first GBJam submission; I look forward to seeing what you do next!
