Short, sweet, and to the point.
Excellent work, your best animation so far. Everytime you seem to add a new element, from bullet casings to blood splats to blood on swords, but it all has come together flawlessly. I could complain about length but it was like 2 minutes of....well madness. The animation seemed far smoother and you definately stepped up with the simultaneous animation of both of them. Aggregation had some of that but it was very sporadic and had lots of pauses, this gave me a head ache of joy flipping between two characters killing as beautifully as any other movie has had a chance at.
Sanford and Deimos are some bad ass characters, and I was hoping for more developement but then I remembered, this is Madness Combat, not a book or a 2 hour long movie, this is M-A-D-N-E-S-S C-O-M-B-A-T. The new background animations and even some of the plain camera angles and effects were above expectation, although I doubt you can top all of the amazing flame work you did in MC7 and 9 Excellent work champ, loved it, now I have to watch it a few hundred more times, L4D2 will wait.
I always have to feel reviewy so I will give one criticism, although most of the blood animation was fluid, some of the new blood had no physics too it, it looked kinda like a paper towel blowing in the air. It also hung around too long, I know it would be impossible to reanimate every blood thing so there has to be some continuity errors but some seemed way out of proportion.
Well, thats all I can complain about, length isn't a complaint, its a flash movie, not a blockbuster.
Take your time, this shorter one was beautiful.
