I wanted to hear some dubbed dialogue in which one of them says, "Let's run to a convenient open space where we can fight and not break our parents' furniture!"
Some of your "hits" were clearly misses (since you don't want to actually hit somebody in the face), but were shot form the wrong angle. Near misses should not be shot from the side, as the viewer can see that they are really misses. Over-the-shoulder or from behind one character works best when simulating an impact. You figured out this out in a few shots, but didn't in others.
I love that you shot in wide so that you can follow the fight choreography (because when a fight scene is all chopped up into small pieces it often means that the performers can't really fight), but don't forget close-ups -- not just of impacts but of facial expressions -- to break up the scene and maintain visual interest.
I definitely liked the "choose your own ending" aspect, but would have really been impressed if there was a bigger decision tree with more choices along the way. Next project, perhaps?
