	Ejemplo: -l 20 -q 10 -f -g
		cada presion de tecla mostrará 20 caracteres
		esto continua 10 veces (10 presiones antes de que termine)
		una vez que termina, fallará
		todo el texto es verde
 
	También note que reqionar ` saltará directamente a "hackeo" (o falla)
	Este código es un espaguetti, puedo considerar limpiarlo
