The Looking Glass is a Yume Nikki fangame that features spoken dialogue and flavortext when interacting with objects and characters. The game also features light adventure elements, such as simple puzzles and increased interactivity in the normal world. Unlike most fangames the player character is capable of leaving her room, and begins the game in her classroom at her school.

You play as Irene, who discovers a hidden world after falling through her mirror. The game follows her as she explores this new world after coming home from school.
