The Wardrobe

I'm not 100% sure how much time you get for this trophy. Using my walkthrough, you will finish the game in around two hours, which will unlock this trophy. Writing the walkthrough, I took a little under 5 hours with some pausing/save reloading and still unlocked this trophy. To be safe, I will say you must beat the game in 4 hours to unlock this trophy. Please let me know if you can confirm an exact time for this.
