Don't be fooled by the 90s cartoon-styled visuals, as this game has some rather disturbing stuff in it. Given the content of the source material and some of the trolls that are being introduced, it's heavily implied that the terrifying content will only get worse.
As per Nightmare Fuel policy, all spoilers (including those from the source) are unmarked.
Act 1
- The sheer amount of child endangerment scattered throughout. Imagine that you're out on some errands, and the kids that you are babysitting get attacked by weird, shadowy abominations while playing out in the yard. In an effort to escape the monsters, one of your children gets sucked into a mysterious portal straight into a highly dangerous Crapsack World. Yeesh. Joey can actually get eaten by one of the monsters if she takes too long to get to the attic. This is the only time in Act 1 that you can get a Game Over.
- Partly cut-off dialogue from Jude in the portal room and a conversation between Joey and Xefros implies that Jude saw his mother disappear/die, possibly at the hands of the same portal that Joey went through.
- When playing as Xefros, examining various things in his hive and using different items on them can bring up may facts about what life is like on Alternia, especially for Lowbloods. Alteria appears to have a Fantastic Caste System where the lower castes must eventually get jobs serving the higher castes, and that's if they're even still alive by then. If that wasn't bad enough, Lowbloods are also much poorer compared to other trolls, and apparently they must order certain items online quite early in life because they can take years to be delivered, so they have to decide which profession to take when they're still very young. You're also more likely to die as a Lowblood, and that's not because of the naturally shorter lifespan. You can get culled for making the smallest mistakes, even if it wasn't your fault, you're more likely to have your neighborhood attacked by drones, like what's happening in the game at that moment, and it's also extremely dangerous to play sports because of said drones, the nature of the sport itself, and other trolls.
- Xefros's hometown being attacked by drones. Just imagine being there at the time, where the building you're in can get blown up at any moment. And some drones don't even kill any trolls they encounter immediately, but instead snatch them away to be killed later, in what would most likely be a much worse way. Good thing you can Take Your Time in this game. Xefros himself ends up getting trapped under the remains of his balcony after it gets blown up. And the ending scene of Act 1 reveals that the Heiress was the one who called the attack. For a selfie.
Troll Call
- Chahut Maenad is massive compared to the other trolls we've seen, wears creepy clown makeup, carries an axe, and both her pants and said axe are coated in various low bloods. To top it all off, her eyes are a shade of red, which are not unlike Gamzee's eyes upon becoming sober. A comic by the game's staff members involves her showing Joey and Xefros her scrapbook. Said scrapbook contains pictures of trolls she's attacked so badly they've been pixellated. While it's Played for Laughs, the fact that the pictures are censored implies that she kills in very gruesome ways. Even worse, the book also includes survivors, whose pictures are also pixellated.
- Kuprum Maxlol is implied to be a psychic on the level of Sollux. He is aware of what happens to the best psionics (conversion into Helmsmen) and is thrilled by the prospect of being converted into a living battery for an Imperial warship, with his backpack being reminiscent of the tendrils that the Helmsman was chained to. He is introduced as a fanatic supporter of The Empire, and carries around the energy-draining Folykl Darane on said backpack. His dynamic with Folykl is reminiscent of a parasitic relationship, albeit mutualistic in nature.
- Folykl herself is pretty damn terrifying. She has no eyes as a result of a condition called Voidrot, which affects goldbloods and causes them to be constantly dying. In order to survive, she needs to drain another troll's psychic energy like a parasite. That said, she's not actually evil, just bad-smelling and unpleasant to talk to.
- Amisia Erdehn at first looks like a cute artist... but her description mentions cutting off heads and the fact that she makes her own paint. This all but says that she cuts off the heads of trolls and uses their blood as paint, and judging by the colours on her smock, it seems that even higher blood castes are not safe.
- Cirava Hermod gouged out their own eye, and the injury resulted in yellow veins extending across nearly half their face. Why would they do that? To avoid the fate that awaits psionics, being turned into a power source for an Imperial warship.
Act 2
- Joey can convince Chixie to give up her ticket to Jeevik Week by effectively ratting out to Marvus that she's planning a protest. While Marvus turns out to be cool with it and Joey just wanted his help convincing her it was dangerous, Xefros is horrified at Joey's recklessness and gives her a piece of his mind for it later. And for good reason - Joey very easily could've gotten Chixie killed for treason.
- The penultimate "puzzle" of the game. Marvus wants Joey to kill a troll from the blood caste that a wheel stops on. When she objects to this, Chahut beats up Xefros and takes him as a hostage, forcing Joey to backtrack and fake a murder.
- This is the moment that Joey's singular confidence backfires horribly. She made friends with trolls of every caste because she had ignored Xefros' repeated warnings about how nasty highbloods - especially pupleblood clowns - can be. Xefros' paranoia was very well-founded.
- The music that plays during this stage is quite terrifying. Each car has a slowed-down version of its theme, but with ambient sounds and honking. The Rustblood car in particular has an additional noise that sounds a bit like groaning and is quite unsettlingnote .
- The third colour ends up being purple, which results in Baizli Soleil attempting to murder Joey, only for Xefros to shove him off the train and onto a bed of spikes on the train couplings below. There's no Gory Discretion Shot or anything, we actually get to see see Baizli's dead body. When the two return to the purplebloods' train car, his "sister" Barzum is writhing on the ground in agony because she can no longer feel Baizli's presence. Meanwhile, the other purplebloods on the train are celebrating the fact that Joey and Xefros were able to actually kill one of them. If Joey talks to Marvus in between her "killings", he'll reassure her that "no1 who matterz to tha plot is gonna die :o)". Remember that saying that the more meta a Homestuck villain is, the more dangerous they are?
- What's worse is that Barzum isn't just freaking out about the fact that she can't feel Baizli anymore, she's also screaming because she's experiencing his death.Barzum: AAHHHHHHHHHHHHHHH I CAN FEEL IT!!!!! I CAN FEEL IT!!! AAAAAAAAHAHAHAHAHA HIS HEAD MY HEAD OUR HEAD!!!
- What's worse is that Barzum isn't just freaking out about the fact that she can't feel Baizli anymore, she's also screaming because she's experiencing his death.
