I had a grin the whole time I was playing this, it's oozing charm! The complete and outlandish despair from the NPCs never got old haha.
You have a very valuable framework for a really good casual game here. I read in your comments you were a bit unsure on what music would fit, if I may suggest, I loved the humor that comes from the painter being completely unfazed by the panicking crowd, maybe double down into this with stereotypical classical music or something classy, like he truly believes in his art.
