Wow.
The manga panel sequences were very well done. Great storyboard and animation.
Clearly there was not enough time to clean up everything and put color and audio in them, but still very impressive work!
As others have pointed out, a progress indicator for each level would've been great. Could be a kill count or just a progress bar at the bottom of the screen showing how much more is left of the level. I felt some were a bit on the long side.
The dueling section was also a nice change of pace!
Good job, team! Oh and this is my final score!
