Lovely job with the game! I already technically left this feedback elsewhere, but there were a couple things that could make the premise even funnier in execution:
1. The ability to make the walls messy along with the floors. Heck, if the cat is able to climb walls a bit, that is also a nice bonus too!
2. Maybe you would get bonus points for making especially significant objects messy? Such as the bed at the top of the house for example XD
