Abandoned Area: The Museum of the Strange and Unusual. It had troubles in its early years and there were always doubts about its completion, but after the events of fifteen years ago no one has gone in or out...until you.
Adrenaline Makeover: Beth is written as a foolish sort of girl with a crush on Merrick. She slacks off in school and writes silly notes to friends during class. However, despite being trapped in the museum and scared out of her mind, Beth starts solving puzzles and leaving messages for Merrick. She tells you that she "almost solved the final riddle". It is shown that she is very smart at math and physics, but often doesn't apply herself in school.
Always Night: Justified, as the whole game takes place in one night, and can easily be beat in one or two hours if you know all the solutions.
Ancient Tomb: All over the place, especially in the "Tombs and Curses" and "Funeral Rites" exhibits.
Apocalyptic Log: Windlenot's tape recorder and Merrick's diary. There are also photos and videos of the two teenagers fleeing in fear.
Backtracking: Loads. There are ten Ixupi and each pot has two components, so the player will often find the two parts of a pot in completely different sections of the museum. Once the pot has been assembled there are multiple locations for each Ixupi, some of them very far apart, so if you don't run into the Ixupi at one location you have to visit the others.
Artifact of Doom: The Ixupi pots. Windlenot laments ever having brought them to the museum, and Beth and Merrick sorely regret fiddling with them.
Big Bad: The Lightning Ixupi, considering that he is the last one to be caught.
If that is anything to go by, then the Wood Ixuoi, almost always the second to last to be caught, is his Dragon.
Bookcase Passage: In the library there is a secret pot compartment revealed by pulling out a book. There is also an opening in the back which reveals the hallway to the power plant, although it is not hidden when you find it.
Bottomless Bladder: There is only one toilet in the entire museum, and it's all the way upstairs, past a handful of puzzles. Windlenot has a bedroom in one of the museum's towers, accessible only by elevator, and he lives there full time. If he ever had to pee he'd spend twenty minutes just getting to the bathroom.
Blatant Lies: "You can back out at any time." Then they leave you with the gate locked.
Bragging Rights Reward: After you beat the game, you get the opportunity to walk through the museum without fear of being killed by spirits.
Chekhov's Exhibit: In the main hall one of the first displays you see is that of a prized jade skull, which is said to be one of the largest jade items in the world. However, the glass is shattered and the skull is nowhere to be seen. You do indeed find it later, next to the body of Merrick. He took it to use as a weapon. It turns out that there was a jade Ixupi, and Merrick died because he had the object in his possession. Jade is the Ixupi that ultimately claims the last of his life essense and his spirit is found inside jade's pot.
Cobweb Jungle: Subverted. No one has set foot in the museum for fifteen years, and yet almost everything works perfectly, like the lights, the electricity, the puzzles, and the security cameras. The dead bodies and some songs on the jukebox are the only things that show their age. Floors are still shiny, the water lines are still active, and there's not a cobweb or speck of dust on anything. Even the bodies are a little suspect: Windlenot and Merrick look pretty good for being dead so long.
Convenient Cranny: Subverted, in that the crannies turn out not to be so convenient. Merrick hides inside a hollow lion, but because he is clutching the jade skull he is killed anyway. Beth hides in the basement wall but she is eventually caught by fire. Windlenot is seen in the underground cavern, in the middle of drawing some kind of symbol, but the walls are made of stone and it is stone that kills him.
Closed Circle: You're locked in the grounds to begin with. Taken Up to Eleven once you're inside the museum; you can't even go outside.
Clock Tower: The, uh, clock tower. Complete with darkness, melancholy violin music, creepy moving shadows, and clockwork mechanisms.
Creepy Basement: The basement power plant. The hallway to reach it is decorated with skulls and skeleton hands. The power plant itself is fairly innocuous, if it wasn't for Beth's long-dead body in the wall and the final boss Ixupi, Electricity.
Developing Doomed Characters: To some extent. The characters have been dead for fifteen years, but the museum is littered with their personal belongings: a planner, report card, letters, photographs, diaries, voice recordings, video recordings, and, of course, their interactions with you when you release them from the pots they've been trapped in. We find out a lot about Windlenot's tragic personal life, Beth's poor performance in school and her crush on Merrick, and Merrick's fascination with getting into the museum.
Drum Roll Please: A snare drum beat is the only part of the soundtrack in the "Man's Inhumanity to Man" exhibit.
Dysfunctional Family: The Windlenots. They are thoroughly embarrassed by Hubert and eager to disown him. His wife forces him to stop contacting their son.
Merrick's family may qualify. He and his father moved into town together and there is no mention of his mother. They seem to get along well, however.
Easter Egg: And how. Some of them are random events that are triggered by you walking around. Some involve clicking things repeatedly or in a specific order. They seem to fall into two categories: terrifying, and hilarious.
Ghostly Goals: Although they have been imprisoned against their will, each of the dead characters has something to tell you when you release them. Windlenot warns you to leave the museum. Beth advises you about puzzles. Merrick...well, Merrick freaks out about being in the pot and losing Beth. But you can hardly blame him.
Hearing Voices: All over the place. In the Theater, you can hear indistinct oratory (lines from the play Hamlet) and applause. In the "Man's Inhumanity to Man" exhibit, there are angry mob yells and distorted screams. The puzzle room has a tortured-sounding man saying things like "get away from meeeeee!". The service corridors and the Underground exhibit have screams for help woven into the soundtrack.
Instant Runes: Subverted. Windlenot was in the middle of drawing a rune on the ground when he was killed.
Inventory Management Puzzle: You can only carry one item at a time, either an Ixupi jar or a lid. If you find a jar or lid that goes with a corresponding inventory item, you get to combine them, but they are then treated as one item.
Jerkass: Your "friends." They lock you in the place, then nonchalantly talk about the kids that disappeared in the museum and how "they never found the bodies." Real funny, guys. Thanks a lot.
And, at the very end, the newspaper announces that "four teenagers" were the first on the scene. They bullied you into staying the night...and then took all the credit!
It's Probably Nothing: At the beginning you hear a bone-chilling howl and a very faint warning ("get out, get out! They are so evillll!"). Your loser friends try to play it off. "That was just a dog howling." "There was something more than that!" "Well, I think this place is just getting us all spooked!"
Living Shadow: There are some points where a shadow moves along the wall. It has no apparent purpose but to scare the daylights out of you.
Losing Your Head: The Man's Inhumanity to Man exhibit features a guillotine with a dummy whose head you have to cut off to reveal a clue. There is an unpleasant noise when you do this.
Man-Eating Plant: It won't hurt you, but it is implied that there is one in the "Amazing Plants" exhibit. An Easter egg makes one of the plants moves on its own if you stand in the right place for a few moments.
No Budget: The cartoonish appearance of the Ixupi is the game's biggest flaw. The budget seems to vastly increase for Shivers 2, however.
Non-Fatal Explosions: You're standing a few feet away from an enormous power generator which then blows up so spectacularly that it destroys a whole section of the wall, revealing the museum grounds. You haven't got a scratch, of course.
No Romantic Resolution: Merrick doesn't think too much of Beth (he does mention she's kind of cute), but he still takes her with him to the museum. Beth has a major crush on him, but there is zero implication that he ever felt anything strongly for her (aside from his anguished inquiries about her fate when you release his spirit, though that seems to be more about regret for bringing her into this mess). They split up after the Ixupi are released, and though they help each other by leaving notes, they ultimately die far away from one another. It doesn't look like Beth ever even told him how she felt.
Nothing Is Scarier: This game really makes you feel like you're all alone in the museum... until a spirit pops out of nowhere and steals your soul.
The songs on the jukebox in the clock tower. Although they were recorded innocently, some of the songs have deteriorated and sound creepy. You're also listening to them all alone in the dark, shadowy tower, after quite possibly seeing a frightening Easter egg.
Police Are Useless: Two teenagers and the eccentric, well-known creator of the town's running joke go missing in the same day. Merrick has spent his last weeks trying to find out anything he can about the Professor. Clearly the disappearances are linked, but it seems that the museum was never searched. Its security is nonexistent. For fifteen years no one heard a word from Windlenot, or about the fate of the museum, and no one thought it was worth poking around EVEN A LITTLE BIT? There's no telling if the police would have solved the puzzles and found the bodies, but there's nothing to suggest they even TRIED.
The Ruins I Caused: At the end, when you have blown out the power generator, the wall of the basement collapses completely, and your four terrible friends come bumbling through the wreckage to find you, surveying the damage from a high slope of ground.
Rule of Scary: Many of the Easter eggs. The only things in the museum that can harm you (and are alive and moving around) are the Ixupi, and yet you can see glowing eyes accompanied by a hiss, and multiple instances of human-like shadows moving across the wall. They are still very shocking, of course, but their presence doesn't make a lot of sense in context.
Safe Zone Hope Spot: There could be an Ixupi in almost every room, even if it seems safe enough.
Stalking Is Funny If It Is Female After Male: In Windlenot's diary we read that Beth, who has a crush on Merrick, has been following him after school. Windlenot thinks it's very funny, because at the same time, Merrick is following him! He also remarks that Beth is "quite pretty" and finds the situation delightful.
That Was the Last Entry: Merrick's diary in particular, but also Windlenot's, as he discusses Beth and Merrick. Merrick's last entries are written from inside the museum, in a panic, and he says something to the effect of, "I'm going to hide in here! They'll never find me!"
The Corpse Stops Here: Subverted, in that although you are the first person to find the bodies, they are fifteen years old and it's fairly clear that you didn't kill them. One must wonder how their cause of death will be rationalized by the police.
Turn Out Like His Father: Something that Windlenot's wife, Mary Elizabeth, fears. You find a scathing letter from her "advising" (read: threatening) Hubert to cease all contact with their son Geoffrey. Hubert is an embarrassment to his family because of his eccentricity and his single-minded drive in the seemingly hopeless task of building his museum. Hubert does stop contacting Geoffrey...but not because of his wife's letter.
What Does She See in Him?: Spoken nearly word-for-word in a note from Beth's friend. Merrick's into "dead mummies and stuff"! What do you see in him?!
