Excellent tone and direction as a whole. I think more could have been done to play/toy with the audiences expectations, there was so much tension and buildup and dread and it kind of fizzled out by the end with not much of a conclusion. With meta works like this it can be easy to rely on self awareness as a crutch for a truly gripping plot or any kind of shock value, but as these kinds of stories have become more and more common, its important for them to really try to play with what they expect from a prospective audience.
All the same however, It's clear you did a lot with what you've been given and wanted to get out of the story. The presentation similarly is all top notch and I was very compelled all throughout. Good Job.
