I think this kind of animation has been spread in Internet since a long time ago, but never is to late to share the wisdom. This animation in particular is made by Hyun and appears to be the parody of Jackie Chan’s “Drunken Master”.
These cartoons are really simple but they remind me the times where toons and video games didn’t need to have a realistic image to give us lots of entertainment, when the leading roles were simple pixels on a screen and we had great times giving them life through our imagination.
I might be old, but I gladly can say that I really enjoyed those first animations.
Also please check the animation “League of Legends: Stick Figure Spotlight”. It’s pretty cool:
