At the beginning of the game, right after the tutorial [spoilers] if you choose to free the dog it will acompany you 'till the beach and then it will be kidnapped by birds BUT if you choose to play with it then a giant tree branch will fall on the dog and kill it
You can see dead birds falling dead while wallking on the streets at some point in the middle of the game
//A hamster (sort of humanized) knocks another hamsters, takes it off camera and stabs it. There's blood on this scene as well
If you interact with the trash on the beach, Misfortune talks about a time she almost suffocated with a plastic bag over her head including the phrase "I almost died"
[Spoiler] You see a kid, from waist to feet, hanged in their house
You don't get to see them actually hanging themself but you see half of their body hanging
// Also, not the case of kid dying but there might be a scene where Misfortune accidently uses drugs (I couldn't find a warning specifically for it so I'm telling it here)
// [Major Spoiler] You find out Misfortune is dead from the beginning while crossing the street, you see her body covered by a sheet and a flashback of her death
it's implied in the diary of misfortune, because she could feel "warm water near her bottom". she also talks about it, but only if one clicks on the drawing.
When little misfortune goes down into Benjamin's basement and then climbs through the secret door, she does a bunch of wet farts and its actually disgusting but supposed to be funny
Misfortune follows a voice in her head and leaves the house alone until late at night without telling her mother. Has a "running away" sort of feeling which might be triggering
Yes.
Major spoilers ahead ; //
At the very end of the game we learn that Misfortune has been dead since the beginning of the game. Once she sees her corpse it flashes back to Misfortune turning to look at an oncoming honking car. There is screeching tires and an audible thump.
