Yume Nikki was a game made by Kikiyama and 2017 will be the tenth anniversary of its final (?) update. It's an exploration game where you explore the dreams of a girl named Madotsuki, a girl that refuses to leave her room. Her dreams are strange and mysterious, with a lot of stuff inviting speculation on Madotsuki's life outside of her dreams.

This book acts as a guide on going through Yume Nikki and also features my interpretations of things in the game. There's also a few chapters on things surrounding the game such as fangames and supplementary material. It is organized in a Twine format and it covers Yume Nikki stuff pre-2017.

This version on itch.io is pay-what-you-want, because I understand that people wouldn't want to pay for somebody's rantings on a free game upfront!

If you're reading this in June, consider checking out the Dream Diary Jam, a game jam dedicated to making a Yume Nikki fangame! Even if you can't make anything, check out and support the people participating!

And of course, check out the original game!
