Fairly well done, just not my taste of story telling though.
The animation is decent, character drawings were good. The backgrounds were a bit meh. Lots of open space with shapeless buildings with tons of filters over it. Personally I would just trace a couple of buildings and then mimic others around it, you really made it look like you tried to reinvent the wheel, but then came with a block, filtered the fuck out of it to make it look round. The voice acting was good though and carries the story well. That said everything worked out well animation wise and it was enjoyable to watch.

The story and atmoshpere was my main problem. Maybe it's because of watching series like dead woods, game of thrones, walking dead etc that my standards are to high for a simple flashmovie.
But lets face it, you know where the story is heading ( hopefully ), so why foreshadow so much? We know the guy is coming for him, he already attacked something nearby and he is extremely powerfull so the last scene didnt come as a suprise. Feeling a bad omen and then still getting surprised is what I think is better. So him finding a burned out cottage would been better, because then when they add extra guards we could have thought that the city was safe and in worse case scenario that the guy would sneak past them to get to him. Instead you gives us the ending as he is apparently able to kill entire towns with a knife and fireworks. Imagine how cool the final scene would have been if we didnt know the guy was coming for him at all.
Atmospher wise you start off with a nice survival touch. The hunting scene, though adding some comdedic relief, cut those factors out. Suddenly it becomes clear that these characters can fuckup mayorly without them biting the dust. What makes it worse is that they rather stick to their character traits after being close to death. So for me there is currently no atmosphere, so I am rooting for the masked guy.
