Decent engine but the design feels rushed. I would have liked an injury/fatigue system, when you tackle some jerk 5 times in a row, he should stay down.
I'd respect this game more if it had anti-cheat measures implemented, like when 3 people gang up on one and simply kill that person over and over, but never attacking each other of course. It ruins the game entirely.
This is such a terrible game... so many poor design choices were made. Very little skill is involved, it's all memorization and luck, two very volatile ingredients that I don't expect the average flash coder to master.
