I feel the legs and arms rotation through sticks should be applied on the world system rather than local.
Correct me if I'm wrong but right now it looks like when I push the stick on the right the char will move his legs/arms forward whatever direction is facing, which means the stick orientation must be adjusted every time the char is flipping, and given how fast and randomly he can spin sometimes it's just humanly impossible to do.
If it's set on world system the player would just have to take the character position in account and no more his rotation, which would make the use of sticks more interesting.
