Rabid Mets!
The Rabid Met knocked into the air when Axl fell in? Priceless. The voices were done really well and I can't tell you, as a megaman fan, how nice it is to see a well done animation that isn't 'spites', 'sprites' and oh... altered 'sprites'.
Even the little dizzy Met on the credits was really creative and well thought out. You should make more of them. In a sea of redundant sprites, your animations shine. :D
