I like this ninja dude.

I like this a lot. I am going to try putting him in the game to see how the anim looks.

Yay!

I updated the sprite to include a ninja star thowing loop for far away enemies.

Confusing, but sooocool/lethal..

Do you mean the sprite is confusing or the explanation of how he steps back while readying an attack?

Just that there's so many pics.

Steve, if you like it, why don't you rate it?
You know, 5...

...wow. That's all I can say. Wow. Wow. Wow.
5!!!!

Ok I've rated it. Right now, I can only do one attack per enemy, but if I like both of them I'll do two ninjas - one that uses each attack.

Can I use this in an Android game that I am developing?

If you want I can mention that you made the sprites.

That's tough to say, considering that the original author doesn't seem to visit here these days. If the game is in some way related to something on this site, I would think of it as acceptable; if it's a commercial or non-related closed-source project, most likely you won't be able to use the graphics without contacting their original creator.

At any rate, the game source and fan game kits can be found from the downloads page. As far as I know, the fan game kit is licenced under CC 2.0, and the source under the GPL. Most likely the ninja graphics are only included in the source packages.
