It's not bad, the music is pretty cool. The only reason I didn't vote higher is because it's really short, and I realize you said it was a pain to animate but it would be nice if it were a bit longer.
Reviews for "Amon vs Agent 47"
The animation is actually pretty decent. Overall, nice movement. Some attacks could have been a bit more 'powerful'. Maybe take out a frame or 2. Way too short to be uploaded though.
its fun to watch for the first time but thats all and its just a small loop so 2 stars
