Egomassive, there's still the matter of the yellow key doors on the way down there.
This level was... Well, I really liked the avant garde storytelling. However, the gameplay and level design were severely lacking. I would say more thought and practice put into design would really compliment your story. And as for the story itself, I enjoyed it, but I would have enjoyed more structure, as it seemed mostly a bunch of things that sound cool instead of one unified event in Juni's past. I understand it is supposed to be mysterious, but I still think you could benefit by starting stories off more tamely.
One thing I did like was the "keep running" sign. I know that seeing "LET ME OUT" flash across the screen could have sent chills down my spine, if only the level itself were a little more unified and coherent!
