Hitting the funny bone.
I'm not sure if you were trying to hit the funny bone with this one, but I found this to be very amusing. Somewhere in the midst of two Crono's fighting each other without any discernable purpose, and scenes of blood spewing, it struck me as humorous.
Beyond that, you did well with making the fight sequence fluid between the Crono's. It wasn't dull or repetitive, as one would find in most sprite battles. With the perspective tricks I could see you were making sure this was a step up above the expected, and you succeeded with that. The only problem that I would have would be the scratchy music. The sound effects, though, I didn't mind (contrary to what others have said). I found them to be appropriate for what you were going for here; a random sprite clone war. ;)
