Overview
Unknown Exist or UE is a traditional Japanese Yume Nikki fangame. It was made by Umidanu (うみだぬ) aka Itsutsuhashi/Itsubashi (五ッ橋 / イツバシ) in RPG Maker 2000.

Gameplay
As usual, you begin in a girl's bedroom which she won't leave, then fall asleep in her bed to enter a peculiar dream world. The game is saved by interacting with Kaede's desk. The objective is exploration and collecting effects in order to achieve an ending.

Plot
UE stars a girl named Kaede (かえで), who refuses to leave her room. Not much is known about Kaede or why she has shut herself in.
