Need some form of audio
I think if you wanted your animation to be one of those that you had to read to understand, you could have at least made the text/conversations appear more slowly, kinda like one of those silent movies.
Plus the submission desperately needed some audio. I am not specifically saying that I am giving you 4/10 for no voice acting. I mean even a bit of light-hearted background music from the Audio Portal could have sufficed.
Otherwise, at least the animation was smooth and the story was to a small degree interesting.
