Wow...
This was very, very good, but it was like a teaser... there wasn't enough of it! I think that this should either:
A) Have ALOT more attacks
B) Have an enemy AI to attack that fights back
C) Have multiple attacks work at the same time (black guy punches as the grey one shoots at him, ect ect)
D) Have all of the above! (although that would take a ridiculous amount of work)
Very creative, and I love the art style... This is a small amount of excellent work.
