None of the puzzle solutions felt too abstract in the first playthrough.

After the first run, I watched the short film to guide me to the final achievements. These puzzles were more abstract and head scratching, thus the reason for the film. You are encouraged to watch and hunt for clues.

Unfortunately, it's been two weeks since I have played. I don't remember if playing a second time with the clues shared more of the story...I don't feel like I was enlightened on anything more.
