Ahhhh this is so cool! I'm a BIG fan of yandere love sims, but I'm ALSO a big clown/commedia del'arte nerd!! Seeing a Pierrot and Harlequin (or his other name, Arlecchino) is very exciting. I love their dynamic, it mimics their historical rivalry and their love triangle with Columbine. One much like the triangle here, though she always goes with Arlecchino. So glad to see we can smooch BOTH here!
One thing that stuck out to me was the design choices with their shapes. Harlequin has always been the one associated with diamond shapes, as well as bright colors- though the red and black scheme is more popular with him in recent years! Pierrot meanwhile almost always wore all white, with more flowy/poofy clothes and often black pom poms. I would expect to see more polka-dots, or at least a less patterned look. I'd be super interested to know why those choices were made!
