Answer 1

A Multiplayer noob? Skipping a few steps i see.

In your Node2D.gd set the 'ip' var to be that of the 'host' on both devices as "127.0.0.1" is assgined to be localhost

This can be found out in a multitude of ways with the easiest being to call IP.get_local_addresses() or IP.get_local_interfaces() and selecting the appropriate one

On the host device (the one designated as server) also do

net.set_bind_ip(ip)

not important but the lines in game.gd

var p1 = preload("res://player.tscn").instance()

and

var p2 = preload("res://player.tscn").instance()

Seems weird to preload the same Packed scene twice so it should be like

var player = preload("res://player.tscn")
var p1 = player.instance()
var p2 = player.instance()
