not letting me use .include? (trying to write ruby game)

Question

I'm trying to write a text-based ruby game, and I can't figure out what's not allowing my code to use the .includes? method.

These are the errors I'm getting:

game.rb:31:in `home': undefined method `includes?' for "run":String (NoMethodError)
    from game.rb:20:in `call'
    from game.rb:20:in `play'
    from game.rb:69:in `<main>'

If I use the if move == "run" method, it works fine, but when I do include? this error pops up. I'm not sure why it lets me do == but not .includes?

This is my main game.rb code:

require './levels'
include Levels

class Game
  def initialize(start)
    @quips = [
        "You died. Noob.",
        "Nice job, you lost.",
        "Looooooserrrrr."
        ]
    @start = start
  end

  def play
    next_room = @start

    while true
      puts "\n---------"
      room = method(next_room)
      next_room = room.call
    end
  end

  def home
    home_text

    puts "    Do you run out to see what's going on or stay inside and hope the problem goes away?"

    prompt; move = gets.chomp

    if move.includes? "run"
      return :town
    else
      die("Your house catches on fire and collapses on you.")
    end
  end
end

a_game = Game.new(:home).play

and my other file levels.rb is this:

module Levels

    def prompt
      puts
      print "    > "
    end

    def die(why)
      puts
      puts "    #{why} #{@quips[rand(@quips.length)]}"
      Process.exit(1)
    end

    def bad_input
      puts <<-TEXT

      TEXT
      return :die
    end

    def home_text
      puts <<-TEXT
      You wake up to the smell of smoke in your room. Jolting up from your bed, you 
      look around the room and see a heavy cloud of smoke covering your ceiling. There
      are piercing sounds of screaming outside, coupled with terrorizing roars and howls.

    end
end

Any help is appreciated. Thank you.

You have includes? in your code. The method is include? (no 's')
