This is a rather unique and fun quiz game :)
The graphics and animation are nice, and the fighting moves are well executed and made.
The quiz was rather unique, instead of the usual generic one, you've made it into a fight with a nice scene after each answer. That deserves points for being really creative. It was fun to see if we got it right or wrong by the scene.
The only things I would suggest would be to make the difficulties more varied like including different characters and questions. Although small, it would be slightly easier to make the answers being accepted by the enter key instead of clicking, typing, then clicking again.
