Problem with my movement code (enemies movements linked to player ones)

Hi!
I started learning how to use Godot recently and I'm currently trying to create a first project that is a puzzle game on a gridmap when everytime you move from a cell to another, every enemies moves according to a "pattern" (think Crypt of the Necrodancer movement system but without the rythm part).

I started thinking and working about the game and its mechanics 3 days ago, trying to understand how I could code such a thing since I'm a beginner. I found kidscancode, it helped me with the grid-based movements and while I still have trouble to understand some things (like tween), it's much more clear in my mind now.

Anyway, here is my problem: as I said I want the enemies to move when the player is moving. Also, if the player is colliding with a wall, I don't want the enemies to move.
So far I've almost succeeded, even if I think the code I tried to re-wrote with the adjustements I wanted is far from perfect. But everytime I try to walk into a wall, the enemy is still moving. I want it to stop.

I tried everything that came to my mind for the past 2 days before reaching out here for your help. Any advice is welcome!

Here is the two script I wrote. The first one is for the player, the other is for enemy.

PLAYER SCRIPT

extends CharacterBody2D

var animation_speed = 10
var moving = false
var coll = 0
var tile_size = 64
var inputs = {"ui_right": Vector2.RIGHT,
			"ui_left": Vector2.LEFT,
			"ui_up": Vector2.UP,
			"ui_down": Vector2.DOWN}

func _ready():
	pass

func _unhandled_input(event):
	if moving:
		return
	for dir in inputs.keys():
		if event.is_action_pressed(dir): 
			coll = 0
			player_move(dir)
			print(coll)

@onready var ray = $RayCast2D

func player_move(dir):
	ray.target_position = inputs[dir] * tile_size
	ray.force_raycast_update()
	if !ray.is_colliding():
		var tween = get_tree().create_tween()
		tween.tween_property(self, "position", position + inputs[dir] * tile_size, 1.0/animation_speed).set_trans(Tween.TRANS_SINE)
		moving = true
		$AnimationPlayer.play(dir)
		await tween.finished
		moving = false
		coll = 0
	
	elif ray.is_colliding:
		coll = 1

ENEMY SCRIPT

extends CharacterBody2D

var animation_speed = 10
var moving = false
var tile_size = 64
var vec = Vector2(-1,0)
var inputs = {"ui_right": Vector2.RIGHT,
			"ui_left": Vector2.LEFT,
			"ui_up": Vector2.UP,
			"ui_down": Vector2.DOWN}

func _ready():
	pass

@onready var player_col = get_parent().get_node("Player").get("coll")

func _unhandled_input(event):
	if moving:
		return
	for dir in inputs.keys():
		if player_col == 0 and event.is_action_pressed(dir):
			enemy_move(dir)


@onready var ray2 = $RayCast2D


func enemy_move(dir):
	ray2.target_position = vec * tile_size
	ray2.force_raycast_update()
	if !ray2.is_colliding():
		var tween = get_tree().create_tween()
		tween.tween_property(self, "position", position + vec * tile_size, 1.0/animation_speed).set_trans(Tween.TRANS_SINE)
		moving = true
		$AnimationPlayer.play(dir)
		await tween.finished
		moving = false

	elif ray2.is_colliding():
		vec.x = vec.x * -1
		var tween = get_tree().create_tween()
		tween.tween_property(self, "position", position + vec * tile_size, 1.0/animation_speed).set_trans(Tween.TRANS_SINE)
		moving = true
		$AnimationPlayer.play(dir)
		await tween.finished
		moving = false



func _on_area_2d_area_entered(area):
	get_tree().reload_current_scene()

I hope someone could help me with this! Thanks a lot in advance!
