S⁄⁄D

Overview
S//D is a Yume Nikki Fangame made by Xom. (Xom has also produced the Yume Nikki fangames Tec, and Older ) The game stars a boy named Mark. It's made in RPG Maker XP unlike most Yume Nikki fangames, and plays a bit differently than most.

Gameplay
Unlike most Yume Nikki fangames, Mark gets to the nexus right from his door. You return to your room by pressing the D key or by selecting Eject from the menu. You can save at the bed, and interacting with the vase with a flower can bring up options if you want hotkeys off or on.

The hotkeys in S//D are
 * A - effect actions
 * S - return to normal
 * D - return to your room
