Hey guys, Teld here, just want to give a little more info for anyone who's interested, and first of all: Do not play this map if you don't like Naruto.
Secondly: Hero levels will not affect gameplay at all, they are simply to represent your personal stats, as you gain hero levels by winning tournaments. You can save or load your hero level at any time, as long as you are not playing single player.
Thirdly: all credits have been appropriately assigned in the help tab.
Most of the characters are balanced, though they arent completely. However the testers and I have been able to beat each other as any character.
If there's anything else you'd like to know send me a pm and I'll tell you all you need.
