Yume Graffiti is a fangame. As of now, it's currently in version 0.02. It strives to be darker, similar in tone to Me or .flow. The game features a boy/girl named Yomika, who lives in a treehouse. He (using male pronouns for convenience) is presumably a hikikomori, as he cannot leave from his room. There's also a ladder down to the ground, that leads to a sealed off area around Yomika with crystals on the rocks. The game has 16 effects, and no ending currently.
