3. Blind spot/short range, all enemies have it, most normal enemies have a shorter range than you do and get stunned for a split second, which is enough time to continue your punches over and over and over, killing them without getting hit at all, and I know that at least the last two bosses have a blind spot, all you have to do is run at them, use a jutsu at close range, and spam punches. Which usually allows you to drain it's life with minimal interruptions.
4. Points, it's so easy to get them and fill your stats to their highest. it's only a thousand each! The cost should rise by at least a hundred for each increase.
Otherwise it's a cool game, albeit a little repetitive.
2/5, Like Pyromaster222 said it has potential but I'll point out a few things I noticed.
1. Jutsu, if you save your chakra (Quite easy) you can beat the bosses all pretty quickly by running at them and performing them as fast as possible because from the second you start casting until it finishes all nearby enemies take damage. I don't know if that was intended, but it's spamable and overpowered.
2. Button spamming, whether for jutsu, punches, shuriken, or healing you can do them all within half a second of the last one. You can get through almost all normal fights by spamming the punches non-stop, Boss fights are equally easy by spamming jutsu like I explained above.
