Yet another suggestion ^.^

Ok, so here it is
You should add an ele system, you can get your 1st ele at genin, 2nd at jounin and 3rd at anbu, also you can buy trench knives, to add your ele into, and get a special jutsu. you can also fuse the ele's. yh, im sure youve heard this all before right? yh, now for the original bit( i think) to get your ele, you need to buy chakra paper. Just like the show.

Good sugestions but the thing about the paper ive seen it on another game already so its not really original but in all these are some good suggestions
