Not funny

Not funny, it suck, and it's to short.

Sheep...who are ninjas.

I actually found this a very funny little cartoon. Sure the animation isn't spectacular, but it doesn't need to be because IMO the joke is solid. The evil ninja sheep's eyes are the best man.
Good luck with any future flashes ;)

enjoyable

excellent work

...

you get a one because ninja gaiden is in the title.

Tru Dat.

I agree ninja gaiden is not a game for casual players, it's a bit short.
