Thank you so much! I didn't have as much time as I wanted to make more levels but I will definitely revisit it in the future to add some more fun stuff.
You can add some puzzle with falling-domino effect with room items.
In the childhood, I played a flash game with a bit similar graphic design with Tom and Jerry (or regular cat and mouse) and it was too hard for me as a kid.
It would be much easy to play now but I don't remember the name of the game and website.
