In the earliest builds of Yume Nikki, in-game text was not given windows outside of the game's menus; this feature was not added until Version 0.05. Curiously, while overworld text is generally sparse, Version 0.10 features data for a three-line window, far more than what is normally needed. This appears to line up with a text prompt in Version 0.04 – but not Version 0.06 onward – that appears when Madotsuki attempts to return the swivel chair to her desk in the dream world version of her apartment.

Because Version 0.05 is not currently available to the public, it is unknown if this window was indeed used for the prompt in that build or if the text was removed before the idea could be implemented.
