Unknown Exist

Overview
Unknown Exist or UE is a traditional Yume Nikki fangame made by Umidanu (うみだぬ) aka Itsutsuhashi/Itsubashi (五ッ橋 / イツバシ) (TwitterPixiv). It stars a girl named Kaede (かえで), who refuses to leave her room.

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
Not much is known about Kaede or why she had shut herself in.
