While I consider Yume Nikki the game as one of my favorite video games ever, the manga is an atrocity. The way the characters are portrayed don't match the way they react within the game at all. The story of the manga seems to be completely out of place due to the genuinely dark nature of the game. The art is quite an eyesore, the characters have no mouths, Madotsuki always has her eyes closed in a very irritating way, and the surrealistic nature of the game is not captured at all in the manga. The art is so bad, that it is hard not to laugh at. I was eager to see what kind of story could be made with the material that the game provided and I ended up being incredibly disappointed. The game had no dialogue in a show don't tell sort of manner, while the manga foolishly fills the entire story with poorly thought out dialogue that ruined the haunting atmosphere the game always excelled in. The story is flimsy at best in the manga because it seems that they didn't want to include too much information about the world, but also decided that it was important not to add a story anyway. This leaves the story feeling like it lacks the depth one would look for and it was better off not having a story to begin with in order to maintain how open to interpretation the game was. The manga should have had either a fleshed out back story or no story at all. I consider Yume Nikki the video game to be one of the most atmospheric, disturbing, and artistic games out there. The manga doesn't live up to that praise in any way and it is one of the worst things I have ever seen. Also, for anyone who claims that the manga could never capture the spirit of the game, read Yume Nikki: Anata no Yume ni Watashi wa Inai. In conclusion, I would definitely recommend avoiding this manga for fans of the game.
