Is it broken? i remember playing this a while back, but now it's no longer loading! can someone confirm this?

im stuck on gotaro i think this is some sort of glitch as hes not attacking and the tutorial seys im suposed to do a counter attack

Really nice

This was a really nice game I did think the Gigantic Water Snake was a bit much but still pretty fun, You have Demonstrated some good skills here, I didnt find any Negitive points at all and if I did it was nothing really, and you seem to have Organized it well also, This is a very Acceptable flash and i was pretty impressed with this right from the start, so props to you on a good piece here, anyways keep making fun games.


I'm attacking Gotaro and his health isn't going down. It takes all the fun out of a game when the enemies are invincible without a certain combo. I think that's how to progress, but it says I have to go something 10 times and I'm at less than 25% health and not progressing, so I don't see any point in continuing. :\

Super difficult but very rewarding, artwork is great along with the animation. Some sections are complete bullshit(w a t e r f a l l) but I love it. I'd love a sequel!

(Oh btw anyone who's stuck on the waterfall.
When a fox fireball flies at you, dodge it then use final thrust to pass through the waterfalls. I can't guarantee you won't get hit, but anyone who is just stuck on it and isn't worrying about the no hit thing, here you go)
