I'm not sure how much of what I've read so far is in which update, but reading through this 2 things really stand out that could use improvement:
1. The use of flashes is more irritating than scary. The repeated flashes at the title card especially seemed pointless, in that they didn't seem to be expressing anything within the story.
2. There's a lot of misinformation in this story. It's true that fiction will always have some, because researching everything is impossible and not worth it, but it's still a good idea to at least look up any trivia about popular topics or important plot points. For example, it's probably fine that a mention of Faust is immediately tied to Goethe, since it's reasonable for the characters themselves to not know about Marlowe or the puppet show versions. However, claiming that 5 Nights at Freddy's would be banned in Japan for child murder is downright strange, and moments like the lawyer not showing anyone the will (which is almost universally a criminal offense) and the mention of "reinstating citizenship" left me wondering what sort of setting the story was supposed to be taking place in.
