Touch Detective

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. 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.

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.
