OOOOOOOOOOOH YOU COOKED!!!!!!!!!!!!!!
I love the mood of this. It's so ominous and I really enjoy the look of the elevator too!! The silence makes it really introspective, in a way, like why are you there and what the deal is with the big tower. The twist with the theme was also really neat - instead of descending, as you'd expect, you're going deeper in another way.
Amazing job!!
