Hmm..
Even for a kick-ass computer like mine... the action is a little slow (Not lag) The rabbit guy just "moves" too slowly. (Know what I mean? Hes not action paced) Everything else you said about Ninja is true... except one thing. You never see them... even their eyes... oh and one more thing they are more like assasins. (They never go out and kill somebody unless they're in danger or/and have a contract to assasinate somebody If they fail they will be hunted down and killed. (<---- Absolutly no point to anything I said.) Very good flash, but please speed it up a notch or two!
