I favorited this a long time ago
...and I must say that I am glad I did it or else I wouldn't have found it anymore.
Really good work, even though noone speaks I understand what the characters are trying to say. The music fitted the movie because of the graphics and because noone talked. I liked these points a lot.
Maybe make something different, with a different story. You don't have to make a sequal just for the same popularity, maybe another movie/game with the same kind of art of graphics. I wouldn't care if the characters wouldn't talk either.
