Multiple occurrences of suicidal intent, one mentioned suicide, and one self sacrifice.
If you get triggered by this subject easily, then be wary of the Corner Rooms, as each of them are designed to make a character want to commit suicide/sacrifice themselves.
Probably not deliberate and not all that frightening, but there are some scenes that come on quickly/are like jumpscares- even though they may not be intended as such. (Usually happens Whenever Sent gets mad, or whenever the mc has a panic attack)
Often there is blood. Characters regularly cough up blood/get nosebleeds, and that's where most of the depictions of blood are. However, in chapter 17, an amputation occurs (actual amputation not shown dw), and a character's sprites feature a bloody stump from there on out.
There were some fires in which pets died, but no people died within those fires. One fire was a house fire, in which a character was said to be inside at the time, but escaped safely.
Rae is ableist, and uses language like "cripple" to describe certain disabled people. He's called out for his asshole behaviour, and the game makes it clear that he's not in the right.
one of the characters has claustrophobia and is seen suffering from panic/anxiety attacks after getting on an elevator and being in a room where the ceiling is closing in
