I do not watch much anime, but I would go the long length of saying it is a naruto themed game.
Now I see you probably have taken lengthly reviews of your post to make sure it does not infringe of any copyrights, based on what I have seen, I have to say good job to you.
Your post is well formatted, designing it must have been a pain I assume.
Your artwork for a 2d pixel game, if actually your teams work, is close to what I would consider professionally done.
But the idea still stands about international copyrights based on certain aspects of a naruto themed adventure game.
Do you have a license to redistribute even if free an interactive application using Naruto based content?
If I am completley illiterate
and for some odd reason this is completley opposite of naruto, then I must say, I could worship your work.
Now if my suspicion is correct, I would not even worry about being caught, just the fact it may be an illegal act.
So on top I am just asking, and basing ideas off what I have seen.
