Here's an IGN spotlight of the game. There's a lot more animations shown in this video.
This is a RunStart Animation and a Push Animation cut together. The RunStart played at the start of a new stage and the Push would play occasionally while riding forward.
EpicSkater was a mobile game I helped make with a few of my friends back in 2011. I did all of the Animation and Rigging in the game. It's an old project, but I had a lot of fun and learned a lot while making it.
