Be forewarned, some parts of this game will require the most cryptic actions - even in the context of Yume Nikki fangames - to let you progress, but don't let that sway you from giving Yume Tagai a try! Visually it holds itself high above the masses, even in this particularly pixel-art-focused genre already filled with powerful artists, and I'd say it's worth looking into for that alone; it has its fair share of particularly memorable locales as well.
