* AwesomeMusic: The game soundtrack is generally very well done, but "Cosmos of Fear", the theme for the Planetarium, is especially awe-inspiring. The dramatic score "Scenes from a Postcard" is also very beautiful.
* HoYay: When Chloe meets Inspector Daria face-to-face in case #3, hearts appear over her head and she instantly decides to become 'Miss' Daria's apprentice.
* JerkassWoobie: Lynsey. She isn't especially friendly to anyone who doesn't have a doll and then there's the [[spoiler:kidnapping people and playing with them as living dolls]] thing, but you can tell how lonely she really is. Her only art is of her crying hysterically as Mackenzie takes her doll away.
* NightmareFuel: The planetarium owner in the first game. Wears a sinister trenchcoat, creepily obsessively devoted to his daughter, has the mouth of a leech, [[spoiler: tries to turn both Mackenzie and Penelope into mind-controlled people-dolls]].
* NoExportForYou: After the Japanese versions are released, the North American lozalized versions are usually released in the same year. No news of Touch Detective 3 since May 2018.
* {{Squick}}: Some of the ingredients in Antoinette's pastries seem like they would be inedible--eel shortcake.
** Thanks to presentation style and general quirkiness of such a random, undefined world, plus the fact that characters are never given specific ages, it leaves things open to some implications that really wouldn't fly in a more down to earth setting. If you actually give them two thoughts though, they can definitely become this. One example being the references to how the big-built, muscular Dover (who is pretty clearly meant to be an adult characters) has the hots for the young girl, Penelope. At another point, Eric, a swindler who's very obviously an adult, makes a pass on[[KidDetective Mackenzie]], calling her "good-looking" and talking about taking pictures of her. Other older characters often call her cute too, nothing bad in itself, apart from the fact that the dialogue seems to imply sometime that they don't just mean it in a "cute kid" way.
* TheUntwist: In the second game. It is such an untwist that you wouldn't see the fact that it's a twist coming.
* TheWoobie: Silver, especially when it comes to insecurities about his voice. After his accident, his song comes out as so terrible that [[spoiler:even the Cornstalker, who had arrived to steal him, just laughs and decides it's not worth it.]] Silver's reaction to that alone was heartbreaking.
