A character is said to have been abandoned by someone who he saw as a father figure, however at the time he was an adult. The same character is stated to have been an orphan, it being implied he was abandoned by his bio parents.
As stated by the creator in a tumblr ask/post, Henry's father was abusive to him growing up, and it is stated that Henry often mutilated William -who adopted Henry's son's name David- in grotesque ways, and grew to hate him for taking his deceased biological son's name.
In DSAF 3, the player gets stalked by Dave if they refuse to bring him to their new restaurant. In one route, Dave notes how he has security cameras installed around the player’s house.
Children are murdered throughout the series, one being noted as particularly grusome. Another character who made it to adulthood is implied to have been abused in his childhood.
Spoiler(?)
Although not mentioned directly in the game, supplementary content from Tumblr lore posts reveals that Henry isn’t exactly kind to animals..specifically referencing the mistreatment of a lion from his circus.
In Project Save the Kiddins (created by the same person behind dsaf and featuring the same characters), there's a reference to pedophilia, but it's only brought up to deny it. Dave says, “What the hell is wrong with you, Davey? Are you a child molester or some shit?”
Rest assured, I’m not a kiddy diddler or anything like that. I’m just an eggplant man who gets a kick out of shutting down shitty haunted pizzerias.”
Jokes here and there about things like “leaving with your hymen intact” being a dialogue option or people saying Matt the virgin is “a creep” and “what is fucks your’e bitch r*pe” (spelled like that I have no idea what it means and I think that’s intentional )
Jack gropes a stripper and the stripper ends up getting arrested. I'm not sure whether it was consensual, but the word 'grope' makes it seem like it wasn't…. There’s a lot of weird jokes like that in the games.
Ronaldo is repeatedly implied to use human meat in his cooking, with Dave even noting that he “used it effectively”— strongly suggesting they relied on Ronaldo to discreetly dispose of bodies
At the end of DSaF 3’s good ending, Henry ends up being choked with sausages
Dave in dsaf says “strangle them (referring to the kids) with a string of sausages… I’m so fuckin’ creative.”
The game repeatedly uses “kiddy strangling” as a euphemism for child murder
Multiple character are inferred to have had their heads squished into phones with it being described to have happened in a character's backstory (however this character is mentioned to be a horrible person and getting his comeuppance)
The main character is missing two front teeth, and is stated to have lost them via another character hitting him with a hand crank. This is only said outside of the game by the creator however
It is stated that Peter (DSaF2 Phone guy) attempted to crucify Dave Miller (Purple Guy) to get rid of him. As well as tapes in Dayshift 3, stating Henry had done nonconsensual procedures on Dave in his sleep, following his first spring lock failure.
In dsaf 3 an antagonist abducts an infant with the intent to kill (in the bad ending the player helps him) however in the good endings the player stops him and the infant is presumably returned to it's parents
While not shown it's mentioned in the good ending of dsaf 2 that the company the characters work for sent a character off to Vegas with a brick of cocaine hoping he'd overdose, the character remains alive.
Dave created clown animatronics. Henry himself once took on a clown persona ..he also served as the ringmaster of a circus that featured clowns. Additionally, there are multiple instances of Dave talking about clowns.
There are moments where there are hallucinations in the second game of a ghostly dog, and a majority of the good route of the third game is especially due to going into another form of reality, leading to a grotesque landscape in the form of the "Void"
The m slur is used and a cop with dwarfism is dressed in a baby mask, playing on the “people with dwarfism are children, look like children or should be infantilized” trope. “Psychopath” and “crazy” are used a lot
optional dialogue from the first game, it’s not extreme and the series matures afterwards, you have the option to make a joke about jews and your character says “curse phone guy and his jewish ways”
The creator of the series, DirectDoggo, has not explicitly stated that any characters are LGBT, but a couple of major characters are implied to be mlm. In quite a few endings in all three games, one (or both) of these characters die.
there are end-credit scenes in every dsaf ending, if you count still images. some endings in dsaf 3 feature multiple images that showcase a sequence of events
Spring lock scenes as well as multiple times in cutscenes blood is shown. A lot of concepts in this game are gorey and disturbing, however a lot of it is in dialogue
