* Cal's eight-heart event, if Sol tells him to back off from Tammy because she's "[theirs]". Cal, who [[ChildhoodMarriagePromise promised to Tammy when they were kids that he'll marry her when they're older]], breaks down crying, feeling betrayed by Sol, but then [[IWantMyBelovedToBeHappy begrudgingly accepts their decision to court Tammy and tells them to take good care of her]]. The game makes you feel guilty of breaking up their wholesome ChildhoodFriendRomance just to date Tammy, especially since the only other way to do so is by bullying her into being too nervous to ask Cal out.

The game makes you feel guilty of breaking up their wholesome ChildhoodFriendRomance for it, especially since the other ways to do so are by bullying Tammy into being too nervous to ask Cal out, or leaving her to die early in subsequent runs.

* The "Tangent's Cure" ending, due to having the biggest death toll both in terms of background living beings and named characters. Specifically, Tang and Instance successfully create the bioweapon under Lum's orders, and the whole colony moves into the ''Helio'' as the virus eradicates all Vertumnan wildlife in preparation for terraforming the planet for farming. However, Cal is killed for violently protesting against the program, Instance commits suicide a few months in, and the surviving colonists are forced to continue living under Lum's fascist rule, not emerging from the ship until 10 years later. This is before getting into the fact that Symbiosis, Socks, any native pet Sol may have acquired, any animals kept in Geoponics for anything other than meat and any animals Sol may have had a good-to-neutral interaction with are killed as a matter of course.

* Sym’s death in a manticore attack. This is especially gut wrenching if you’re romancing him, as it happens moments after you share a first kiss. Even though he eventually gets better thanks to his BodyBackupDrive, Sol (and first-time players) won’t know this at the time.

* Anemone’s brother, Kom, is killed during the first Faceless attack on the colony. Notably, his death is the only one in the game that is completely unavoidable no matter what you do, and it serves as the CynicismCatalyst for Anemone’s storyline.

* If Geranium is the only member of the family to die, Flulu responds by completely shutting down, to the point that Sol needs a certain score in Empathy to get her speak to them ''at all''. If the Empathy check succeeds, all Flulu can manage is an extremely strained attempt at speaking to them the way Geranium would. In this timeline, Flulu's epilogue mentions she and Sol grow estranged over the following years.

* Just like Tammy, her father, Tonin, can die early on, attacked by a manticore on an expedition. If Tammy is alive at this point, she will be absolutely heartbroken by this.

* If Sol doesn't manage to bolster the colony’s food supplies enough to stave off the famine, their mother eventually dies from overwork and malnourishment. You’re then treated to the [[SarcasmMode lovely]] image of your father cradling her dead body, completely broken from grief.
* Unless you manage to find a cure for Shimmer, the airborne disease that plagues the colony each Pollen Season, Sol's father will end up passing away from it. Coupled with Flulu's death, it’s possible for Sol to become an orphan at age 16.
