I don't think I've tried to get passed it too much, probably around 10-15 times but this is most retries that I have on any level.
The mission is to kill 90 guys in 53 seconds and I always fall too short. Usually around 15-20 guys are left when the timer hits 0. Only once I managed to get down to 6 guys or so, but still that isn't close enough.

Any suggestions?

Try to leave brawlers on one side until you get a knife / arrow / bomb from the other side.
Also, get into a rythem, keep on clicking, don't wait for animations such as picking up a weapon, or whenever you hit a color enemy then do the required clicks immidiately.

For example: you get a right, right, left, right enemy. Do all the clicks in fast succession as soon as he gets into your field. The are the only time consuming issues in a speed round, the rest is just clicking fast.

Also, keep in mind that the enemies practically "wait" for you to hit them in this round, so don't stress about getting hit, and just click click click.
