Debris

Overview
Debris (also occasionally known as Debris Dream) is a game made by Harinezumi. It involves an idiot (according to their description in the game's menu) Tatsuki, going to the dream world by sleeping. There is an extra playable portion as an unlockable character in the post-game. It also seems to have glass and glitch motifs, possibly relating to the title of "Debris": scattered remains of trash or wreckage.

Gameplay
Like most Yume Nikki fangames, Tatsuki refuses to leave their room, but has a balcony and video game console with a game called Yoke. Tatsuki saves in what appears to be a diary or journal, and enters the dream world by sleeping in their bed.

Even though Debris stays true to the nature of Yume Nikki Fangames, it adds a few new things such as having locked doors in the nexus, and is known for its many events and attention to detail.

Plot
Debris starts out like most fangames, but focuses heavily on events and the environment to explain Tatsuki and their possible personality/past. After collecting all the effects, there is an extra playable portion as Lefia for the other two endings. Debris can end in four ways, only one being the "True END" (explained in detail on the walkthrough page).
