Woohoo! I've found an Yume Nikki/Ib group! Nice group, btw.
And I remember reading in comments to some other work that these two games could be crossovered, like, Madotsuki can actually be an older version of Ib, who slowly started losing her mind after the events of her game. What do you say?
P.S. That idea became my headcanon for Yume Nikki.
