A very melancholy, and surreal game about a social introverted girl who won't go outside(probably due to some sort of personality disorder) and has disturbing/psychedelic dreams. Draws heavy inspiration from games such as Earthbound and LSD dream emulator.

The developer Kikiyama created the game back in 2004-2007 and has not been heard of for years since (fans theorize he/she is dead and this game was their last cry for help).
Timmy: OMG undertale is amazing!1!1!1!1!

Philip: Oh, that reminds me of a game called Yume Nikki.

Timmy: Yume Nikki? That sounds like a rip off of Undertale!

Philip: No.
