Stop keyboard input from propagating to other nodes

I want to intercept keyboard inputs at higher-level nodes and prevent them from propagating downwards to other child nodes, if possible.
Originally, I was trying to do get_tree().set_input_as_handled(), but input events were still happening in my child nodes.

My root node adds a scene - GameScene - in it’s _ready function:

const game_scene = preload('res://scenes/game_states/game_state.tscn')
func _ready():
	var game_scene_instance = game_scene.instance()

And my GameScene, it adds my Level1 scene in it’s _ready() function:

const level_1 = preload("res://scenes/stages/stage01.tscn")
func _ready():
	var level_instance = level_1.instance()

In my stage01 scene, I have a Player scene that looks at input thru _unhandled_input() function, and does something based on that input.

func _unhandled_input(event):
	if event.is_action_pressed('ui_down'):
		print("Adding 15 points to the player's score")

But, I do not want my Player scene to receive any input. So, in my GameScene, I implemented it’s _unhandled_input() function to mark every input it receives as handled.

func _unhandled_input(event):

But, if I press the ‘ui_down’ key on my keyboard, I still see “Adding 15 points to the player’s score” printed in the console.

+1 as your clear question answered a similar issue I was getting.
Answer for me was to put get_tree().set_input_as_handled() in the _input event (with conditions).
