Very cute! I liked the concept of each pet coming from behind the door. The knocking and then the animation was also really cute!
It took me a bit to get that "messy/clean" was a category and not just based on their behavior. But once I got that, it was cool. I did run into a few bugs and it seems like people have already mentioned them, so I won't spend time on that.
The music selection was a good choice. Very calming!
Thanks for playing/rating Untangled. And congrats on finishing the jam!
