i was thinking that you could "jump" from tree to tree the same way ice mirrors work. to get in and out of the tree there is like a climb comand. also you could just have it stay away to get aroud or make it like a training thing that tains tai and/or stam. also make there be like a jutsu that you learn that alows you to climb the trees. now you dont have to do the training and jutsu idea but the jumping idea is good the others i think mite make it better.
