It's told in an item description that anyone who use gems like Purple Mage, Professor Orange and especially Gold Pig, had to sacrifice one or more of their senses. In the case of Gold Pig or Green Mage, one gem replaces their eye.
The game mentions that every dialogue you witness without the player character being in the same room is said player character spying on who's talking.
The game uses "misleading" language at some points, but it isn't used in an antagonistic way. It is more puzzling or confusing in how it sometimes speaks.
The Maze Monster is very spider like. In new game+ there’s Lewmoth, a moth which is a self insert of one of the game’s composers. Though a bit hard to find as it’s an Easter egg.
The character you play as is thrown into an incinerator, you can dodge all of the attacks but it's extremely hard to do it and it's intended for you to lose
Green Mage explicitly mentions they pulled their own eye out in one of the game's final areas on the main route. It is unshown but spoken of directly. Avoid this cutscene by giving in instead of resisting as soon as the game prompts you when the water gets deeper. You will miss some other dialogue from characters if you take this method, so skipping through text really quickly may be preferrable.
[MAJOR SPOILERS]
All of the characters die in the normal ending, and one of them is implied to be a child with their name in the battle replay and achievements being Vampire Kid. Though they are also all eons old.
(MILD SPOILERS) At the end of the normal ending, and when you beat Cat God in its fight via deflecting it’s attacks, Cat God will try to scare you by zooming into the screen all of a sudden.
It isn't exactly explained, but there is the implication that you as the player are controlling a sentient and sapient character within the game's world near the end of the game. Said character openly asks you to do this.
Someone removes their ability to move or see, and traps themselves in a forest for an unknowable amount of time. This is done out of distress and to inflict suffering upon themselves. It does not occur on screen but is discussed later.
Ok so this is a *super* weird case so bear with. It's heavily implied the character Pink is experiencing some form of dissociation to cope with the fact that they were destined by the universe to kill people they care about, but the implication is very clearly that the presence of alternate personalities in Pink exist to begin with as a form of dividing responsibility.
So, I guess they're mentally ill specifically because they're violent, and not the other way around?? Overall they're depicted as very sympathetic and it doesn't come off as stigmatized despite every indication of the contrary so, I guess it's not too terribly likely to be triggering but also not unlikely either. Tread carefully.

a lost spirit in the castle reveals they committed suicide by jumping inside the incinerator. The main character, Pink, dies by suicide in the normal ending, and if you complete the incinerator unscathed, it’s revealed Pink had attempted to kill themselves there many times to no avail. Rasta Beast also reveals that Pink had pleaded with others to end their life, and Professor Orange had tried to assist Pink in suicide before as well.
In battles the screen regularly distorts, rotates, shakes, whirls and similar effects to simulate hallucinations or instability. Towards the end of the game, the player character is tasked to kill even the embodiments of the world like the sun, causing reality to fall apart.
It's rather heavily alluded to in the "Apocalypse Note" found in Orange Mage's lab after getting your arm back in the second half. The Mirror of Truth may also evoke some feelings of this.
There are heavy themes and allegories to medically assisted death. Characters repeatedly express that they do not want to live, and ask you to kill them. This is discussed in the narrative of the game and handled differently than a real world comparison. The residents of this world are not able to die by any other means, and are being barred from entering the afterlife. This forced immortality distresses them physically, mentally and spiritually. Their longing for death is an escape from a very real "prison" and does not hold much connotation to suicide or depression, in this specific context. Caution is heavily advised for those whom these themes are triggering.
All characters use they/them pronouns, but some will be also referred to as "he" in only a couple of lines of dialog. It is intented that they use multiple sets of pronouns and it is not misgendering.
Everyone dies. No one has any explicitly noted LGBTQA traits, but these could be easily inferred as many of the characters use multiple sets of pronouns and are generally seen as "nonbinary".
To the first commenter: dude. Rasta Beast is right there. Rasta is in their name, and they have dreads in their design. The lovable unicorn is black.
[MAJOR SPOILERS] Rasta could be the first to die if you backtrack all the way to the start of the game and enter Midnight Town first thing after getting your arm back without killing anyone else on the way. It’s very likely not intended for Rasta to die first, but it is definitely possible due to the nonlinear nature of the game’s second half.
(Spoilers) during the game’s final section, you play as Pink, a glowing humanoid who is always nude but has no visible nipples or genitalia. There is a very defined butt, however.
Not literally but the game's themes are HEAVILY interpretable as an allegory, and I'm of the opinon it has a particularly unflattering moral takeaway in this regard.
