S//D is a Yume Nikki Fangame made by xom the creator of Older, Tec and obox. 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.


Unlike most Yume Nikki fangames, Mark gets to the nexus right from his door. You can 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 to toggle hotkeys "S" and "D" off or on.

The hotkeys in S//D are

  • A - effect actions
  • S - return to normal form
  • D - return to your room

Different from most fangames, some of NPCs give Mark a fake effect which will trap him into an enclosed area once it is used. The fake effects have separate options from the real one in menu which have same descriptions, and could be obtained more than one from these NPCs.

Certain chasers and events may cause Mark lose one or all the effects he owned. The lost effects need to be obtained again from the origin. 


(All of the sprites here, including the Statue's, have been doubled in size for convenience.)
