As one of Project Yume Nikki's works, official manga was made for Yume Nikki. It was released exclusively online between the dates of May 20, 2013 and March 13, 2014, in English, Japanese, and Spanish.
Reception
In the time that it has been released, the manga has received overall criticism by fans, although there are some that feel it's a great adaptation to the original game. Most of the fans criticize it for a variety of reasons. Some aren't exactly in favor of the new art style. Others heavily dislike the fact of a new story. Rather than only Madotsuki's story, Poniko's and Masada's are also being told. Another change was that the story was told with dialogue, as opposed to the original which was all about the player's interpretation.
