just a couple suggestions for the game

Luffy: his jet pistol, should have a further reach, if you see what i am saying, because i watch one piece a lot, and it's much longer.

Deidra: a quicker running speed, he is a ninja after all.

Itachi, Quicker speed, when he does that move were he teleports, and kicks you, i would suggest using and dvx: 20 or 15 so they fall really far, it will look much cooler.

also for all characters, i would suggest, using a dvx: 15 on most of the attacks, which are supposed to knock you onto the ground, because it looks more better
