I have 3 sprites A, B and C, each one has area2d attached to it and collision shape

the script for A

extends Area2D
var done = 0

func _input_event(viewport, event, shape_idx):
    if event.type == InputEvent.MOUSE_BUTTON \
    and event.button_index == BUTTON_LEFT \
    and event.pressed:
        get_parent().hide()
        done = 1

And all like that

Now the main node has a script attached to it

extends Node2D

func _ready():
    if get_node("lA").get("done")==1 && get_node("B").get("done")==1 && get_node("C").get("done")==1:
            get_tree().change_scene("res://scenes/scene2.tscn")

But it doesn't work, why?

The error when doing if get_node("lA").done == 1 is

Invalid get index 'done' (on base: 'Sprite').

What I'm trying to do is collect some items, when done, move to a new scene
