The aesthetics are great, it reminds me of a game called "Minit". And the idea of the game and the use of the limitation is very clever, maybe a couple of changes I would make personally would be to reduce a little bit some colliders, and make your own house count as a fireplace.
By the way, at one point I have encountered problems with the camera. I guess you know what point it is but if you need something let me know and I'll go to take a screenshot.
