Sewage

Overview
Sewage is a Chinese Yume Nikki fangame, developed by 天蓝色の约定. The protagonist is named Xuán Wō Zi.

Gameplay
Like other fangames, the object of the game is to explore the protagonist's dreams and collect items. However, rather than directly going to sleep to get to the dream world, the player enters a doorway that leads right to the nexus instead. The items you get don't change your form or do anything at all. Rather, they seem to be the memories from the protagonist's past.

The protagonist can pinch her cheek to return to the nexus, rather than directly waking up back into her room.

Plot
Like most fangames, the plot is never told to the player and is left open to interpretation. The game suggests the protagonist is school-aged, as the game has a world of doodles of cute creatures, and a spot with "My School" as a label.
