sport design – How can enhance this straightforward climbing system?

I used to climb for a short while, like solely a month or two as a result of my girlfriend was doing it on the time, the coach used to name me “warthog” insinuating I used to be a type of meatheads that did not care about climbing clues and simply exausted traying to muscle each wall with no finesse in any respect however aside from that it was enjoyable, I wanna make my climbing system have complexities that may be related to actual life climbing, what are the primary issues that i can add this weekend?

#climbing part
var wall_incline
var is_wall_in_range = false
onready var head_ray =$Mesh/HeadRay
func climbing():
    if is_on_wall():
        if  Enter.is_action_pressed("ahead"):
                checkWallInclination()
                vertical_velocity = Vector3.UP * (power + (agility * 0.15))
                #horizontal_velocity = course * 1
                is_climbing = true
                is_swimming = false
                if not head_ray.is_colliding() and never is_wall_in_range:#vaulting

            is_wall_in_range = false
    else:
        wall_incline = 0  # Set to 0 if there isn't a collision
