One magazine Sayori finds in a store refers to the parodic Do You Lift Club ! mod by the creator CykaDev, and even has "Slavyori" (Sayori's parody from this mod) on the cover.
DOKI DOKI RAIN CLOUDS MOD MOVIE
The movie that Natsuki and Sayori watch has the gender-swapped synopsis of Your Lie in April.
Near the end of the mod, when Sayori finally hits her lowest point, she proceeds to add some cuts with the same scissors she (accidentally) stabbed herself with.
Late in the story, Monika also admits to have tried cutting herself after having spied on Yuri, only to quickly grow bored and unsatisfied from having done so.
Later that same day she finds out about Yuri's cutting habits, and feels no right to judge because of her own episode.
Self-Harm: Sayori stabs herself in the arm with a pair of scissors during an apparent Monika-induced blackout.
Sayori even has a brief flash of awareness that the poems are garbage before being mysteriously compelled to like them.
Mythology Gag: The poems of original game's MC are all a just a list of 20 comma-separated words, a literal interpretation of the original's minigame.
Eventually, after a bit of walking, they do manage to catch a bus.
Missed the Train: Sayori and Yuri's outing involves missing the train back home.
DOKI DOKI RAIN CLOUDS MOD CODE
Mind Rape: Though Sayori doesn't understand exactly what's happening, Monika is using her self-awareness and ability to manipulate the game's code to traumatize her and push her to kill herself with various disturbing visions and nightmares, in several scenes that echo the original game's second act.
I Want My Beloved to Be Happy: Though Sayori is emotionally conflicted over it, she chooses to stay out of the development of the protagonist and Natsuki's relationship, as she doesn't want to ruin it for them.
Invisible Parents: In spite of all the days spent at Sayori's house, there is no indication that she even has parents, and she needs to buy her own food.
If you do, the scene turns from Monochrome to Color, and it seems as if she may change her mind.
At the end of the game when Sayori is about to hang herself, you have the option of rejecting this choice.
That night, Sayori has a disturbing nightmare in which Yuri says she was only pretending to enjoy herself, hated Sayori's company, and only wanted to find out more about the protagonist and his relationship to Natsuki. It's played out as a very fluffy and happy scenario, seeming as if it may help Sayori get over her depression.
At one point, Yuri and Sayori go out on a trip together.
Hello, : In keeping with the source, the player gets to name Sayori's childhood friend, our Player Character in the original game.
Featureless Protagonist: Although the MC from the original game had and retains his particular personality, his rendering is intentionally that of an extremely generic boy, albeit with brown hair instead of black for contrast reasons (originally a fan drawing that has become widespread in the fan community).
Dying Declaration of Love: As Sayori dies on the rope, she decides to have her last words be "I love you" towards the MC.
Downer Ending: No matter what you do, Sayori will die just like in Act 1 of the main game.
Doomed by Canon: The intended audience of this game knows what Sayori will ultimately do at the end all too well.
Deliberately Monochrome: This game is at many low points significantly less colorful than the game it's based on.
Cutting Off the Branches: Though the original game offers the choice of writing poems for Sayori, Natsuki, or Yuri, this mod has the protagonist writing all his poems for Natsuki, which only makes Sayori feel worse about not being cared for.
Sayori will generally entertain these choices, and sometimes attempt to follow through with them, but ultimately reject them.
But Thou Must!: There are several instances where you can select positive choices, such as Sayori writing a not depressing poem, or not hanging herself at the end of the story.
The Bad Guy Wins: Monika ultimately wins at the end, thanks to the Foregone Conclusion.
Another Side, Another Story: The premise of this mod is to go through the story from Sayori's point of view.
