Yume Graffiti (ユメ-グラフィティ)

Overview
Yume Graffiti (ユメ-グラフィティ) or Dream Graffiti is a Japanese Yume Nikki fangame produced by Oudn (Blog, Pixiv, Twitter).

As of now, it's currently in version 0.035. The game features a girl named Yomika, who lives in a treehouse.

Gameplay
In Yomika's room there is a bookshelf with only two books, one being blue and the other, green. The blue book gives access to a sound test. As you progress through the game, you can unlock more music on the sound test screen. The green book brings up the save menu.

By interacting with the pile of grass on the floor, Yomika will fall asleep and enter the dream world. In the dream world, she can find and obtain Effects that will allow her access to other areas or trigger certain Events. She can wake up anytime by pinching her cheek.

Plot
Considering her living conditions, this game most likely takes place at an earlier point in time as opposed to the modern rooms of the other fangames. Yomika herself seems to be in a sort of leaf skirt.

The game's motif appears to be mainly nature-based, with most of the Effects being traditional Japanese demons/outfits/creatures.

Yomika seems to be by herself in her treehouse, possibly because she lives in a forest isolating her from the rest of the world. She cannot leave due to the forest overgrowth, or that it is too dangerous to go outside.

Effects
Dream Graffiti currently has 20 Effects (as of version 0.035).
