Nice work! It's well polished, I liked the goofy visuals, and the meow button was a nice touch at the start(even if it was just for the sound test)
I think it would have been neat if it ended after a few and had a showcase of your "art" to give it some purpose and an end point. Since it was endless I kind of ran out of steam after a couple. Also, when clicking on overlapping objects it doesn't always pick the one at the top.
Overall though it was pretty good
