Great concept, I've never seen this before, which is awesome! I love the artstyle, it looks incredibly polished. I was fighting a little bit with the validation and room placement, as sometimes it would validate, but fail to place the room (even though the correct room was in the correct other room), and going back into the room I couldn't validate again. I had to reset the room. But bugs are the name of the game in a jam, so no problems here :P
Another thing I ran into was a money issue, I think? At some point I got stuck placing furniture because I didn't have enough money, even though I'm not sure how that could be, as I don't think you have a lot of choice regarding the money you spend, right?
Anyway, I would love to see this game fleshed out more into a full little game, would be great and very soothing to play :)
