Yume Nikki

Yume Nikki (ゆめにっき, lit. Dream Diary) is a surrealistic adventure game by indie Japanese developer Kikiyama. The game was created using RPG Maker 2003, but has few role-playing game (RPG) elements. Players explore the dreams of a hikikomori character named Madotsuki (窓付き, lit. windowed). Traveling through her dreams, the player encounters surrealistic horror scenes, such as being swallowed by a large red sewer-creature, meeting a disembodied head character known as Uboa (ウボァ) and a full-screen rotating image of a girl with five arms. The initial version of the game was released on June 26, 2004, with subsequent updates over time, the last occurring in 2007.
