Yume, Shosen Mousou (夢、所詮妄想)

Overview
Dreams, delusions after all  (夢、所詮妄想)(Yume, shousen mousou) is an obscure fangame from the original Yume Nikki made by henaroda (へなちょこ). It stars Kamitsuki (かみつき), a boy who not only refuses to leave his room, but blocks the door. The main recurring theme in the game seems to be adolescence and its many related complexes.

The game has a single ending, which is unlocked after you find all of the 22 effects hidden within the world.

Gameplay
Unlike most fangames, Kamitsuki visits his "dream world" by reading his journal, and only uses his bed for saving. Besides that, it plays like most fangames, the main objective being to collect all 22 effects.

Plot
As opposed to other games, Kamitsuki doesn't just refuse to leave his room but also doesn't want anybody else to enter, since his door is blocked by a bookcase. He seems to have an obsession with video games, specifically RPGs since his computer screen has a sword on it, which you can inmediately find on his room as an effect once you enter the dream world for the first time.
