Acceptable Political Targets: Most of the people that are part of the Black Goat's cult give the excuse that the town is drying up and dying because of too many mining regulations, kids not wanting to stay where they were born, and the government giving their tax money to immigrants and poor people. As Mae puts it, a cult of conservative uncles.
There are some that believe Eide is (somehow) Mae's grandfather, or even a brainwashed Casey Hartley.
Was the cult being honest when they said Casey was a criminal, or were they just lying to justify their actions? Or did they sincerely believe it, but were actually wrong? Or, is it a case of Believing Their Own Lies?
Demonic Spiders: True to its name, Demontower has some enemies that can kill you in a matter of seconds
Hairballs, because once you kill one, three mini hairballs appear and against a group of hairballs, it's hard to overcome a group of 9 or more.
Fire Birds will launch fire balls at you usually between 2-3. Against one, they aren't that annoying, but a group of three is frightening trying to dodge their fire balls while trying to kill them.
Blue Skellie Warriors. Unlike the other skellie warriors, they will lunge at you with their spear when they get close to you, so they are far quicker than the other two.
Knife Guards. They move far faster than the fire birds and they throw their knives shortly after finding a new location.
Disappointing Last Level: Your reaction to Chapter Four depends heavily on how you feel about the somewhat abrupt shift from "open-ended slice-of-life game with horror elements and grounded social commentary" to "totally linear allegorical Cosmic Horror." It also lacks any puzzles or minigames, with all the action happening through dialog and cutscenes. There's also a distinct lack of the sense of humor the game had up to that point.
The nature of the creature that talks with Mae in her last dream is also questioned, from it being the Black Goat to the real god or even another thing entirely.
People have also raised the possibility that the Black Goat is ultimately not even real, and it may be just a bunch of coincidences happening together while a bunch of people, desperate to ensure their town's survival, are doing misguided and unspeakable things.
The fact that Aunt Molly doesn't appear in the final chapter led people to believe that she is among the cultists and point out a lot of Foreshadowing of it. The Weird Autumn update appears to have jossed this particular theory, as she shows up in the epilogue, and gives no indication she knew about what happened the night before.
Fanon: A certain Niche amount of fans have drawn Casey with fur color similar to Mae, mostly due to the fact that his Missing Poster has him in a dark color. Despite the fact that, said poster is obviously uncolored and it was stated in game that he had Orange fur.
Fan-Preferred Couple: Mae/Bea became one almost instantly. The fact that they seem to show genuine chemistry later in the game helps.
Though there are some that do ship Bea with Steve Scriggins, much like there are some with pairing Mae up with Bombshell.
From the looks of it shipping Germ with Mae seems to be the common ship with Germ in it.
It certainly got more steam when a dummied out of the game originally but reinserted into the Weird Autumn Edition, hang out was just have Germ invite Mae over his house and just jump around a trampoline and help her relax a bit.
Mae and Casey is also common with some fans who would like the believe they were a couple some time before the latter went missing but there's no evidence in the game's lore that suggests this, besides being best friends in the past.
Fountain of Memes: Gregg is becoming this thanks to YouTubers making random "shit-post" videos of him and his scenes in the game.
Many people like to quote Mae due to how hilarious and immature her dialogue can get.
Genius Bonus: The Black Goat is most likely a reference to a Lovecraftian Great Old One Shub-Niggurath, which is associated with the phrase "The Black Goat of the Woods with a Thousand Young".
The amount of Fan Fics that take place after the game and after the Black Goat cult was most likely killed, a popular fan theory that Aunt Molly was part of the cult and as a consequence seemingly died with the other cultists, becomes pretty weird when it's rectified that she wasn't part of the cult and probably was never involved with them to begin with. Seemingly rendering most of the angst that comes along with the fact that Mae realizes that she might have killed a family member, especially her mother's sister, for naught.
Bea used to be a happy girl like Mae, but after her mother died her life went downhill. Forced to live with her aging and lonely father, she has to run the family store (which is frustrating her to no end) and can't pursue her dreams of going to college. Part of the reason why she hates Mae when she returns is that Mae essentially threw away the one dream that Bea had left, resulting in Bea turning into this.
Bea's father, Mr. Santello, also qualifies. Devastated by his wife's death, he has become lazy and bitter. Bea explains to Mae that he's still in the midst of a breakdown.
Mae qualifies as well. She's rude, disrespectful, and irresponsible, but she has also been struggling with mental illness since early adolescence and feels frustration over alienating others.
Launcher of a Thousand Ships: Due to Mae being both pansexual, the Playable Character & being able to interact with a Lot of characters. Mae's been shipped with a at least a small amount of them, the most common ones being: Bea, Selmers, Bombshell and Casey. There's a few strange and rare ones like Cole, Lori M. and even Germ Warfare. And then some fans actually go out of their way to ship her with GREGG.
LGBT Fanbase: Gregg and Angus are gay, Mae is pansexual, and Jackie is a trans woman; these facts were very well received and attracted quite an audience.
The phrase "Gregg rulz ok" that Mae scribbles in her journal a few times is starting to become a common saying among fans.
Also another common saying in the fandom is asking "Crimes?" and then somebody immediately replying with "Crimes."
Quite a few quotes in general:
"I'm Lord of the Snack Falcons!"
"Got cups on my ears."
"I'm a total trash mammal!"
"I have nightmare eyes!"
"Bite my entire ass! Go legally brain dead from lack of oxygen from choking on my entire ass!"
"Everything Sucks Forever..."
Gregg's arm flailing animation has spawned hundreds of Youtube videos setting it to various songs.
Bea Bae or Bea is Bae note Bea has been very well-loved by the fandom and with the rise of the term Bae which is a term of endearment used by most internet denizens. Naturally due to how her nickname rhymes with Bea her fans natural took to using this.
Mae is Bae used to a similar effect by fans of Mae.
Narm: At one point, Bea suddenly says "U" instead of "You" and "Rite" instead of "Right"... and not during a conversation on the laptop, either. It's somewhat jarring to see her suddenly speak SMS-talk out of nowhere.
Popular with Furries: While the art style, story, and music are great in their own rights, it's no doubt that some of this game's popularity came from the anthropomorphic animal appeal.
Porting Disaster: The PS4 version is missing a chimney to the left of Lori M.'s rooftop perch, making one of the weather windmills inaccessible, thus rendering 100% Completion impossible. The later version 1.04 patch put it back in.
Portmanteau Couple Name: MaeBea, Angregg, SelMaenote Selmers x Mae., Maesey note Mae x Casey Hartley, and GerMae or JereMae note Jeremy "Germ Warfare" Warton x Mae Borowski . There's also Marbo note Garbo x Malloy. (no, not that Marbo.)
One True Pairing: Gregg and Angus make up for an amazingly sweet loving couple that are absolutely loved by 100% of fans, with some even being disappointed at Bea for believing they might break up, though the game makes it clear that their future is uncertain.
Scrappy Mechanic: While the platforming works well most of the time, performing high jumps is arduous. You need to do three jumps in the same direction without changing in order to high jump. This wouldn't be a problem, but in the early game, before you've mastered it, getting around the rooftops is a pain.
Ship Mates: If someone ships Mae/Bea odds are that they also ship Gregg/Angus.
The main story is only about 4 or so hours, but can easily be stretched out to 10 or 12 in a single playthrough just by participating in the sidequests around town or simply talking to people each day, as each day has new dialogue for every single person in town.
Many players also admitted sinking a LOT of time into Demontower.
That One Achievement: "Seriously!?" is an achievement that can only be gotten by getting every single page on the notebook, IE 100% Completion. The creators themselves lampshade in the achievement description that they didn't manage to do that, and they created the game. It does not help that it's a situation of Guide Dang It!, since there's no hint on what, where or when gives you a new page and people are still finding out what and how many are all the pages.
While "Pumpkin Head Guy" is a pretty good song, it's universally hated by most players due to being a huge Difficulty Spike in comparison to the first two songs.
For some parts of the fanbase, all the band practices are this. Luckily, screwing it up doesn't affect the story any; though achieving both the Maestro and "Seriously!?" achievements require a passing grade on all three. Including Pumpkin Head Guy.
The later levels of Demontower, usually starting with level vii, as the tougher and quicker enemies appear more often and sometimes the area that leads to the boss is surrounded not only by the guards but also by lava. Level VIII is probably even harder than the final level. There are knife guards galore, which are almost impossible to kill due to their fast speed and constantly throwing knives at you, if you manage to make it to the boss fight, the boss is a upgraded knife guard that throws three knives at a time, while also being surrounded by many other enemies, including regular knife guards. It makes Pumpkin Head Guy look easy.
They Wasted a Perfectly Good Character: Some fans wish there was more development for minor characters including Bombshell, Casey, and Germ. The latter actually had a few hangout scenes that explored his character a bit more but were cut from the final game.
Viewer Gender Confusion: From first glance, Mae can easily be mistaken for a boy since she doesn't have many notable features that says she's a girl. Heck, even her name Mae sounds like it could be a boy's name.
Mae is a frustrated, anxious and energetic 20 year old who is basically a female Holden Caulfield. She dropped out of college because she felt like she didn't belong there, had no friends while being there, and was as miserable as she always was. She suffers from dissociation and 'anger problems' and suffered from what was possibly a psychotic break when she was 14, resulting in the Killer incident, and while it takes several playthroughs to find everything that's gone wrong in her life, the sheer amount of terrible events that have happened to Mae is almost tragic.
Angus was abused and neglected by his parents for years.
Gregg has severe doubts about himself and the future of his relationship with Angus, believing that he is simply not good enough.
Bea not having enough opportunity or money, or both, to go to college like she wants. She can only take free online college classes. Her mother died and she's stuck running her sick father's store. Bea lies to her other friends that she's going to college, and Mae inadvertently spoils Bea's illusion of being a normal college student instead of a business-alligator.
