Two saving factors.
Definately a worthwhile concept. I don't think there's much arguing that. As an added bonus, at least you actually went to the trouble to make some real art for this insead of using some crap webcam footage like the majority of Numa Numa flashes did.
The one downer here is that I was actually kinda expecting something along the lines of FF1 vs AYB.
On the whole, though, I like the concept, and it was nice to see that somebody finally *drew* something to use with the music insead of just making a no-talent webcam video.
