Cyclothymic

Overview
Cyclothymic (defined as a mood disorder that causes emotional highs and lows) is a Yume Nikki Fangame made by Fg7. The game was discontinued by the developer at an unknown date.

Gameplay
You play as a girl named Koji who refuses to leave her room, exploring a world she enters by reading her notebook. Like most fangames, the main objective is exploration. There are only two Nexus worlds available due to being a demo version.

You enter Koji's dreams through her notebook, and save at her computer. To wake up from the dream you can either press 9 or interact with the notebook again.

Plot
If the player tries to leave Koji's room, Koji will shake her head. Koji will say a few lines of flavor text about some of the objects in her room if interacted with. Not much is known about the game's plot due to its early cancellation.
