	PORTAL (primera persona) - MÓVIL
	Colócalo como LocalScript en: StarterPlayer > StarterPlayerScripts

	- Fuerza la primera persona.
	- Muestra la pistola de portales y la vida (HEALTH) como en el videojuego.
	- Los portales se crean en la superficie a la que apuntas (pared, suelo o techo).
	  Si no apuntas a nada, usa la superficie más cercana a ti.
	- Conserva el impulso: si caes por un portal del suelo, sales con esa velocidad.
	- Los botones están junto al botón de saltar.
	- Solo tú los ves y usas (LocalScript).
