Yume Nikki

Yume Nikki (ゆめにっき, lit. Dream Diary) is an adventure game by pseudonymous Japanese developer Kikiyama. The player explores the dreams of the protagonist Madotsuki and encounters a number of surreal locations and creatures. The game was created using RPG Maker 2003, but lacks most elements commonly associated with role-playing games such as combat and quests. The game's primary objective is to collect items known as "effects" that grant Madotsuki new abilities and allow the player to progress to new areas, with the game ending after 24 of them have been collected.

The initial version was released for free in June 2004 with subsequent updates over time, the last occurring in 2007. While initially receiving minimal attention, it garnered a cult following since its release and has been cited as an influence on other games. The game was released on Steam by publisher Playism in January 2018. A 3D reboot under supervision by Kikiyama, Yume Nikki: Dream Diary, was released the following month. In addition, a manga adaptation and various fangames inspired by it have also been released.
