- Art Shift: The first game is very much an Animesque Visual Novel, complete with characters communicating entirely in grunts and electronic buzzing (much in the style of its source of inspiration) - the background and tone are bleak and realistic, in-keeping with the Creepy Horror aesthetic. The sequel, on the other hand, has a much more quirky and colourful approach of European Western Animation (á la Cartoon Saloon), with stylised (and animated) character models, full voice acting and lush hand-drawn backgrounds.
- Genre Shift: The first game is a creepy Suspense Mystery with horror elements and traces of humour, whereas the sequel is a light-hearted Comedy Adventure Mystery with elements of Suspense and traces of horror.
- Running Gag: The hat, whether absent or not.
- "Your moustache is troubling me. That thing seems to be longer every time I see you."
- Killed Off for Real: The murder victims, naturally.
- Where the Hell Is Springfield?: The events of the two games take place either in Britain or in the US. Officer James wears a British uniform and talks in an English dialect, the toilet is labelled "W.C."note , and the price signs of the first game's fair all carry '£' symbols. Yet, Grimoire speaks in a (fake) American accent in the second game, as does half of the cast. It helps that the game was made in England.
- Everyone Is a Suspect: Naturally, it is a whodunit after all. the only person not a suspect is yourself, the little girl and Officer James.
- The Summation: Every good mystery has one and you as the player have to piece everything together at the end
- Fair-Play Whodunnit: fits this trope to a T
- Who Murdered the Asshole? you find out that both victims were not pleasant people.
- The first victum hugh was a very lazy and unagreeable old man who was half deaf, he did not get along with anyone at his work and left the funhouse he was in charge of in ruins
- Remmington seems fine at first but as the story goes on it is revealed he is actually part of a Secret hunting society and had stolen the land through a legal loophole since it was protected by law to continue to hunt to the elusive Boggy to add to his cryptid Collection.
- Point-and-Click Map: hiven to you by the mysterious little girl in both games.
- Hyperspace Arsenal: Lampshaded in the second game by both Sally and Grimmoire
- Sally asks where the detective keeps all his stuff and asks if he keeps them in his pockets.
- Grimmoire asks where little keeps putting all her items noting her dress doesn't even have pockets.

- Red Herring: The Fight between Ricky and Charles was set out as a red herring, it even says so in game.
- Hall of Mirrors: The crimescene.
- Craggy Island Fun Fair: Justified because Jerry says it is made to look this way on purpose to give a creepy feeling.
- House of Broken Mirrors: The mirror next to the body is shattered and broken and it is obvious not all the glass shards are there.
- Mirror Monster: Inverted because the killer broke the glass to prevent this very trope and being seen by the victim as he inspected the broken mirror
- Alliterative Name: Bobby Burle, Boggy's Bog, Edward "Echo" Everstone, Richard Remington, Sally Spears, Vincent Van De Peer.
- Awesome Mc Coolname: Edward Everstone. At least Grimoire likes it.

- Cryptid Episode: In the second game, the prime murder suspect is "Boggy," a creature rumored to live in the swamp. The actual culprit was just someone in a costume, but Boggy does exist.

- Shout-Out: Detective Grimoire makes a snarky remark about the guy with the top hat.
- Stylistic Suck: The notebook puzzles feature crude stick figure doodles of the situation Grimoire is trying to solve.
- Swamps Are Evil: Grimoire often goes on about how disgusting and creepy the swamp in while other suspects actually find it rather beautiful. But he does have a point considering the Swamp is the scene of a murder.
- Technicolor Toxin: The poison used to make Remington ill was a green powder.
