The player controls the titular detective Mackenzie as she solves four mysteries in the small town of Osawari. Both the art style and the plot reflect a subtle fantasy mood – for example, the first case is to track down a thief who is stealing someone's dreams. GameZone reviewer Steven Hopper notes that "the game features a unique aesthetic that feels like a Tim Burton version of a Jhonen Vasquez comic."[2] Aside from the main plots, there are also a number of small bonus mysteries that involve much simpler tasks. There is also a Touch Notebook containing a list of major items in the game the player has touched.

The game is entirely controlled via the touch screen. Tapping a location on the screen will talk to a character or examine an object. The player has an inventory of items collected, and may use them on other items or objects in the environment. The player can also communicate with the characters along conversation trees or present inventory items to them to learn new information. Mackenzie's pet mushroom, Funghi, is used as an aid in some puzzles.


  • Rina Ozawa (小沢 里奈, Ozawa Rina) / Mackenzie: The lead character of the game. As a young girl, she runs a detective agency with the help of Cromwell. Her personality is the most "ordinary", in contrast to the otherwise bizarre world around her. Although she's the most mature out of her friends, she can also often gain a typically childish amusement from doing "naughty" thing. She keeps a "Touch List" of things she has touched and what they feel like.
  • Manami (まなみ) / Penelope: One of the girls that lives in the condominiums in town and friend of Mackenzie. Her parents are very rich, and thus she enjoys a lavish lifestyle. However, she is rather air-headed, and has been known to disappear for a time, or even not talk to anyone (including herself, except for pantomime) for a whole week. She is the one who will give Mackenzie all her cases during the game and is one of the main focuses of the first three episodes.
  • Chitose (ちとせ) / Chloe: Another girl in town, and while friend of Mackenzie, tends to be her rival in trying to solve cases. Chloe generally takes actions before figuring out their consequences on herself or those around her, such when she broke into and ransacked Penelope's apartment for evidence.
  • Jii (じい) / Cromwell: Butler for Mackenzie and also a genius inventor. Cromwell is a man who has worked for Mackenzie's family for over 300 years. He is often coming up with inventions, and becomes disgruntled if he isn't given the chance to show them off to others.
  • Nameko (なめこ) / Funghi: A living mushroom that is kept as a pet by Mackenzie and travels with her as she moves about town.
  • Deijī (デイジー ) / Daisy: A goth girl that works at the local boutique, and lives in the apartment above Penelope, having to put up with her loud "ditzy" antics as a result. At first hostile towards Penelope and Mackenzie, she becomes friendly later on.

Mackenzie learns that in order to join the ranks of the Great Detective Society, she must solve four cases and submit her investigation report to the Society. Fortunately for her, several cases seem to pop up around town.

Episode 1 - Robbery. The reality of a fanciful dream
Penelope comes to Mackenzie because she claims her dreams are being stolen. Mackenzie first acquires a special invention from Cromwell so that she can see into Penelope's dreams and understands what happens: a strange creature is seen fleeing from Penelope's just before she wakes up. Mackenzie investigates further and finds a way to enter the Dream World, but finds no one there that can help because the rest of the town is not yet asleep. Finding a way to convince everyone to fall asleep at the same time that Penelope does, she is then able to stop the fleeing figure and reveal it to be the pastry chef in town. The chef admits to the crime, using the crystallized dreams as an ingredient in her Sweet Dream Cake dessert. Fortunately, Penelope and the chef agree that the chef will only take Penelope's dreams once a week.
Episode 2 - Disappearance. The truth hidden in the cosmos
Penelope goes missing, and upon investigation, it looks like her room was broken into. However, it is revealed that Chloe, trying to find Penelope before Mackenzie, broke in and tried to find evidence. However, regardless of Chloe's bumbling, Mackenzie is led to the planetarium and its strange owner, as well as a little girl named Lynsey who seems to like playing with dolls. After catching the owner buying girls clothes in sizes too large for Lynsey, Mackenzie soon discovers that the planetarium owner lured Penelope and now is keeping her in a secret room under mind control in order for her to be Lynsey's friend. Mackenzie is able to rescue Penelope, have the owner captured, and befriends Lynsey so she won't be lonely again.
Episode 3 - Stranded. The miracle of an innocent heart
Penelope claims that an ice fairy is stranded at the ice skating rink, the only cold place in town, but Mackenzie cannot see it though she can sense it. The owner of the rink is tired of living in the cold and is looking to shut the rink down, causing the temperature in the rink to rise and threaten the life of the fairy. Chloe comes up with two near-disastrous ideas for saving the fairy, but Mackenzie realizes all they need to do is make it snow so the fairy can be get out from the ice rink and to a more comfortable location. With the help of the local fortune teller Mackenzie helps Chloe in enchanting an "angel summoning spell" (actually a magical girl theme song), which, through the power of Chloe's will, temporarily transforms Penelope into an angel that can make it snow. The fairy returns home after a parting conversation with Chloe, with it being very heavily implied that they share a requited crush.
Episode 4 - Assault. The tragedy of a past grudge
Penelope claims that a murder happened at the circus in town, though it is only a flea circus, and it's actually an assault. Apparently, the circus used to be a larger attraction, but when it shut down, many of the performers took up residence in town. Mackenzie investigates to find that something did attack the fleas, though initially suspecting a flea as the culprit. However, the supposed culprit flea ends up near-dead himself, in a supposed locked room attack. This leads to an initial speculation of self-inflicted injury, however Mackenize deduces that a human sized culprit could have picked up the box the flea was in and shaken it to cause the injuries. When a large anvil nearly kills all the fleas, the trail leads to Dover, one of the ex-performers. His old circus act, animating tattoos on his back, was ruined due to a flea bite, and has been out of work since, and thus took revenge on the flea circus to try to get back into stardom. Dover tries to kill a flea, however, Mackenzie is able to stop him. Unfortunately, the circus ringleader accidentally kills it anyway.

Following the successful resolution of all four cases, Cromwell informs Mackenzie that she has been accepted into the Great Detective Society. However it transpires that he mistakenly submitted Mackenzie's "Touch List" instead of her investigation report. She is given the official title of "Touch Detective" as a result, to Mackenzie's shame.
