to the question below: I think it's showing how such a life changing disaster can change people in extreme ways, sometimes in a good way and sometimes bad. this guy, unfortunately, turned into a monster.
At the start i was thinking the creator is lazy by not making faces and that he tried to pass it off as artistic, but i saw it's not the case. I really really like this animation in every way... story, music and animation. 4/5. I know dialogue would have ruined the animation... but no dialogue and lip synching does make things a lot easier. just my crazy reasoning for the score.
