Wow... this for sure isn't the type of animation quality you see on Newgrounds everyday. Whenever I see something which is over five minutes long and has such a cinematic vibe to it, I know that I'm about to watch something phenomenal 0_0
The overall animation is stunning and was very captivating, it felt like I'm in the middle of an action-packed movie. I love how you established the bond between the dad and the daughter through those flashbacks and their rivalry in the game. It was also a nice touch having those different districts and having the reds specialize in jumping and the blues in running. I loved the moment when the dad was close to winning and was very focused on reaching the end of the race, since he wanted his district to succeed no matter what, but once he saw that his daughter from the opposite district was in real danger, he immediately went off track to save her, neglecting one of the blue district's most important qualities, "loyalty". Then, they both utilized their district's unique moves to save each other during that dangerous fall.
The look and feel of the animation is also fascinating. The areas that the five racers go through have a neat 3d effect and create this illusion of being massively big. I also like the soundtrack choice and the voice acting, all of the individual aspects of this animation are what makes it so special, it wouldn't be the same without its touching story or those insane action elements. I'm loving this, glad to have seen it ;D
