Cyclothymic

Overview
Cyclothymic (A mood disorder that causes emotional highs and lows) is a Yume Nikki Fangame made by Fg7, who also created .ExE, Repentance and One-WAY.

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 at cancellation.

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

Plot
When trying to leave Koji's room she shakes her head. In addition, just like in Me, Koji can say a few lines about some of the stuff in her room. Being both a demo and cancelled game, not much is known about the games plot.
