I find Golovanova's cartoons of the 1980s to have a really beautiful, fluid animation style, with pretty interesting screenplays as well. My favourite is still "Sweet Porridge", but I really liked this one as well. There hasn't been much commentary about it, but I liked the review by Alessandro Criscitiello that I found on LetterboxD:
"Facing loneliness together through a surreal, melancholic and virtually endless circus act. Beautiful. I'd never stop watching it."
