there is somthing that i think will make the game better its leveling up and diffrent skill settings.
on the editor you could change throwing stats,jump hight and more.
you could add a script to a level that does this: if you kill a certin amount of npcs you will get a skill bonus. you will start only with blocking and attacking and you could learn the rabbit kick the roll the high jump tje throw and more.
what do you think?
