fantastic atmosphere! If there's one thing i would take away from this, it would be the ambiance. The ambient music, roars & yells sells the whole experience. The thing that makes this a dreadful, depressing world is that despite the monstrous sounds outside you'd still rather leave that rusted metal prison. Thirdly the climax, it adds to the mystery & invokes questions. Why is "it" there, what happened back then, what year is it after the millenniums? in summary i loved that it told a mysterious dystopic story in one claustrophobic room in only 15 mins.
