Well, I was doing nothing and I decided to think about the game, and I imagined something really cool, an improved chakra system, because this current system besides ending very fast it is very simple, mine is like this:
You use your chakra until it ends, until normal, but after you finish you will still be able to use jutsus, but these jutsus will consume a little of your life, because in the anime, when the character uses a lot of chakra he gets plenty Tired and I know it can not be much like anime, but I think it's a good idea, and before I forget, increasing chakra capacity is very important.
I hope you like the suggestion.

Description of the character's personality:
He is a lively and outgoing guy, but he knows how to behave in the face of a serious situation, when threatened, he does not pity anybody, if necessary kills the person in question, but only in the last case because he does not like using his jutsus to kill.
Description of the character's history:
When he was born, her parents were fleeing from rogue ninjas, her mother managed to escape thanks to her father who sacrificed to protect them, she gave birth near a lake in front of a volcano in the village of Kazangakure, and after a long time Of fleeing the ninjas rogue she decided to stay in that village, which at first did not seem very good to live.
The boy grew up and got used to the place, and it was his home, his dream was to be the ninja who does missions to the hokage, but they would not be any mission, it would be a very important mission for the village, he would give his life To save the hokage and his village.
To achieve a great dream has to make great sacrifices, so he began to study, to become a shinobi capable of surviving months alone and thus prove their value to the hokage.

Well, the idea is basic but it's very good too.
It would be very nice if you added the function of climbing the walls and walking in the water (when you have or if you have), then when you climb on a wall for example, would spend chackra (in water also obvious) and another function that could be added too Was the function of recharging chackra, could add a command for the character to make a hand position, and in this state he would be vulnerable to attacks.
I hope you liked the idea, as I said it is simple but very useful.

Because I wanted to give a suggestion, well it would be interesting if the jumps did not spend chackra, only the double jumps, because it is annoying to have to wait for the chackra to recharge to jump again.
thanks for see it.
