Grabbing wall slide

This really needs to get tweaked cause no matter your speed you still slide down the wall as if you grabbed it at terminal velocity.
I made a jump towards a wall that was one tile distance and i slide just as far as i would if i was leaping off a cliff and grabbing the wall.
I’ve seen people leap short distances irl and movies and grab a wall and they stop. The don’t slide down two stories from the position they grabbed.
