For people who are unsure about what strategy to use in the language level, this is the best strategy I used to beat the language level without the Cleany 9 door glitch. With this map, you are almost guaranteed to never encounter Marzia during the search more than once, unless Mr. Cleany f*cks you up during the search, also watch out for him in the final chase. Also, remember to check for breathing or ticking sounds from outside of the room doors during the late game, and always have at least one flash bang in your pocket to throw at the door.
