Recently, YouTube streamer aborted his plans to stream his playthrough of the game for fans. In a post on Twitter, Ranboo explained that he had decided against playing the game because he didn't want anyone to feel uncomfortable about what he streamed, and he didn't want anyone to think he had "ruined" a game by streaming it.
He also apologized to anyone who did feel uncomfortable about the stream, saying that he would try to do more research on games moving forward. His audience, which is quite young, may have been particularly triggered by some of the darker elements of the game.
In a thread covering the triggers and issues before Ranboo made his announcement, a Twitter page called Ranboo Updates provided a comprehensive run-through of triggers and issues around the game. Ultimately, it seems Omori was too much of a lightning rod to be worth the play-through.
