Hey Robakh, thanks for playing with it ^^ Ok, the camera shaking thing seems to be pretty popular now ahah
Speaking about pillars, the thing is that if press W to go ahead the character does not stop immediately. So this means that you need to work with A S D on pillars or get Crouched with CTRL. And stop pressing W when you Climb them.
Anyway this is only mine explanation, thanks for the feedbacks :)
