It's weird now that Mega Man is in "Super Smash Bros" now. I don't know if Zero is. Honestly, that game got so massive I lost count a long time ago. I really do love this. It's mostly because of that awesome song you use. I was afraid that you would stop using it after awhile.
Luckily, you kept on! This reminds me of the old sprites used for me in Kirbopher's TTA series. Yes, that was me. Anyway, this was a great start for a first flash movie. It might not be that original, but it's fun.
