Yume Nikki (ゆめにっき) (pronounced /juːme nikki/) is a 32-Bit freeware game created by Kikiyama, a Japanese solo game designer. The game was made using RPG Maker 2003. Its initial release was in 2004, and updates stopped in 2007. YUMENIKKI -DREAM DIARY- is a reimagining of the concepts introduced in the original game. While Yume Nikki was a game about exploration and abstraction, -DREAM DIARY- takes the same characters and locations and places a more puzzle-like formula over them.
