REM-9: The Yume Nikki Randomizer

REM-9: The Yume Nikki Randomizer is a randomizer created by vgperson for Kikiyama’s Yume Nikki. It is generally recommended for those who have played the original Yume Nikki and know how to get around the dream world.

You can randomize the effects locations or lock nexus door but also you can set the ending to require any number of Effects, as well as any number of Essences (new bonus items given by notable “optional” side events).
