The dialogs are ununderstandeble, and the running scenes suck...when u make them run, to give the effect of movement...make ur ground move...
Not much fighting for a "Big Battle"
You have good control of coordinating the music. (starting and stopping tracks). You also know how to manipulate sprites well.
I don't mind that I can't understand the dialogue. But when you claim a big battle, I would expect a lot more fighting.
Nope. Instead, there's way too much running, including chase scenes that seem to go on forever. I could count the number of times there was actual contact with my hands.
The action suddenly moves offscreen and out of sight when Naruto does his shadow clones. Sasuke even seems to just watch and wait as they come at him. That was an opportunity lost in which you could have shown some action there.
You can easily do better. Less talk, more action.
That first running sequence...
... WAAAAAAAAAAAAAY too long. I almost killed the flash because I thought it would be an infinite loop of it. The background needs to vary somewhat or have more dialogue to cue the viewer in to still pay attention.
Secondly, you do not need to have any weird colors for the backgrounds of your text bubbles. Plain white will work just fine.
I will say I am glad you kept the Mortal Kombat music short, as it is one of the most over-used songs in existence.
Finally, I would say you could creat some kind of stopping point, as the flash has no point in endlessly looping.
