Woooh!! I absolutely adored this visual novel! The mystery is so tense and each of the characters all seem so unique and puzzling in their own ways. The way the vn was set up wherein everytime you started a new game it would all be connected like an infinite loop with an amnesiac MC who is as strange and terrifying the more we uncover about them-- Aaa they were done so well that I didn't mind having to play the vn over and over again just to see what sort of plot points I was able to uncover.

To be honest, I'm so lost on what exactly is going on. What's happening to MC and their friend, how are they connected, what happened to the world, why is everyone headless (to be honest I attribute it to MC not able to recognize their faces so they appear headless to them), why that monster is there (maybe it's a hallucination put forth by the guilt MC harbors), why the stories were there and how they connect to the people we were able to get it from (they all seem connected somehow, both to one another and to MC, but never to MC's friend), what exactly is MC's role, are they the reason the world collapsed? Are they simply destroying more to give inspiration to their friend? Or are they releasing all the pain to an already destroyed world to cope?

And also, the part with the Angel in Pitch Black's story being uncovered the more we play through is very perplexing as it feels like there is more to it than just what is being presented. 

Is the friend merely copying the Angel that protected MC (this is my little theory)? If so, what the hell are the relations between them all, I find the friend very intriguing because everyone else has a part in the story that correlates to them, even MC, but friend? Nowhere, the only clues we get is directly from him and even then it's quite sparse. 

But ahhhh, this was such a cool visual novel, can't wait to see anymore you make both in the general visual novel category but also in this universe if ever so!
