HO. LY. SHIT. You just took me back to my childhood, Xiao Xiao, Killer Kazuki, Madness, all that mindless action Flash I used to drown myself after school, everything good about them just wrapped up into one burrito, WITH frame by frame. I love it. Not even mad. There is an insane amount of effort here. One continuous 13-minute shot spanning a ridiculous amount of scenes blended seamlessly together. The scenes themselves and the 3D all came together great. The car junkyard was the craziest scene, all of this was just fucking nuts.
Of course I'm not a kid anymore though, I have my pretentious criticisms. One of the main ones is that it was super obvious when you "borrowed" animation from a video game or a movie, kinda took me out of it a little. Also, the proportions and character shape changed a lot when there was heavy fBf, and it would have been better for there to have been less framerate and more volume/gravity to the animation in some places. But other than that, I loved it. My god, how long did that take you? I'm hoping that (2003-2012) isn't 9 years you spent on this one project. I will cry.
