I remember this Intro Animation and Artstyle from back when i first watched it XD Nice Idea to make a Game out of it. Animations look smooth, everything looks REALLY well made. My Nitpick would be the Gameplay itself. As other have said it is not clear if i hit enemies or not and the hitbox itself feels kinda weird. And maybe a Point System and/or Highscore could be nice to check on how well you did (As well as giving a Reason to punch the Enemies instead of just dodging).
