If you look at it in FbF there are no close calls. It is just an illusion because your eye stays where ninja was 'cuz it cannot move fast enough to reach the ninja ahead so it looks like the thwumps hit him yet he still keeps going. Usually what i do with my (few) dda's is FbF check them to make sure the close calls are 'close'...
I dunno, this was kinda one of those maps you just put off to the side. It was kindof boring and small. And I would not call it fast.. It was not actually that fast he only moved 1 ninja's space a frame.
Overall it was a cool dda but short and not fast.. I will have to give you a plain old 2

though you shouldn't tag a dda as "playable." A dda counts as nonplayable.

Cool.
