Strange how that overly dramatic music went so well with that animation. :) Simple but effectual! Bit weird you can't really differentiate between the flies though, as car as gender goes, considering it's a romantic kind of short and all. Not that flies look all that different to the common eye, but with this kind of cartoon it'd seem like the common approach to maybe add some eyelashes to one, or differentiate between them by color, or some of those other gender-based stereotypes we use for such purpose.
I liked the animation though! Quick, methodical, with a clear protagonist and flare for drama.
