1) Whenever Temari jumps, she would go invisible
2) When Shino falls, he turns invisible, not jump
3) When someone gets KO, the body moves a bit, which may cause something if they were near a wall, and be stuck in it if they get KOed
4) To become a Genin, you need to have 1 more kill, than the kills that they are asking for
5) When you die and you see the fighting screen, not the black background, and see the character screen, it is possible for you to die if you are near someone who is hitting you. If they kill you, it's a kill, not a KO then a kill.
6) Naruto's rasenshuriken apparently does no damage

EDIT:
7) You cannot block Neji's 64 palms, it causes the opponent to turn around which causes an open hit
8: You cannot block aerial attacks, some enemies stay in the air when they get hit up and hit the ceiling
9) Neji's 64 palms mainly does lots of damage, no damaging chakra points, which means it's suppose to do more damage hurting the chakra
10) When 1 Neji uses 64 palms, and another does too (like almost at the same time), you would not be able to see the 2nd one cause the 1st one took the 64 palms image

EDIT:
11) When you crash/log out while you were being attacked (I think) you then lose your save file
