Main Easter Eggs in ddlc!:

Special Poems:

At the beginning of each run, three special poems are chosen to be shown throughout the game. There are a total of 11 special poems. The poems can be associated with certain characters.

Unused files:

Beta sketches Note: As of Version 1.1.1, these files are not present in the game files anymore. Almost all of the girls have unfinished sketches, showing them with different arm positions. Noticeably, Yuri doesn't have beta sketches.

Beta background sketch There's an image showing CG of reading with Yuri, except for the background being only sketched.

Natsuki's unused pose Note: As of Version 1.1.1, this file is not present in the game files anymore. An unused head position for Natsuki turning her head away from the view can be found in a folder called "old2" inside of her sprites folder.

Yuri's unused expressions In Yuri's sprite files, there are some unused expressions. The first one is named "Hisui.png" which shows Yuri smiling with big, purple pupils (Resembling those when she's dead) and her tongue slightly sticking out. "Hisui" is likely a reference to the game Tsukihime, the first visual novel Dan Salvato played. Hisui has several sprites with pupils that blend with her irises. The second one is named "y7.png", and it shows Yuri angry with obsessive eyes.

nused font

There is a font "y2" (with a standard font name of "as i lay dying") that is not used in any poems within the game. This font was most likely intended to be used in Yuri's Wheel poem, but was scrapped before the game was released.^{<a href="https://doki-doki-literature-club.fandom.com/wiki/Easter_Eggs#cite_note-3" ]<3]<="" a=""></a>}<a href="https://doki-doki-literature-club.fandom.com/wiki/Easter_Eggs#cite_note-3" ]<3]<="" a=""> </a>

Yuri's "greyed out" CGs

The grey versions of the CGs are supposed to show up in the credits if the player has not seen them during their gameplay. The Yuri CGs that take place in the Literature Club are unmissable because the player is forced to go her route during Act 2, consequently making their grey counterparts in the game files unused.

"Are you sure you want to quit?" prompt Easter Egg

Prior to version 1.1.1, if the player tried to quit the game through the menu during Sayori's suicide scene, the "Are you sure you want to quit?" prompt would be distorted and a cut picture of Sayori would flash rapidly between its normal and negative versions. It has since been removed, but the images still remain in the game's files.
