Gameplay
Your Diary is a romance visual novel in which the player assumes the role of Tomoki Nagamine. Much of its gameplay is spent reading the text that appears on the screen, which represents the story's narrative and dialogue. The text is accompanied by character sprites, which represent who Tomoki is talking to, over background art. Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character sprites. Your Diary follows a branching plot line with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction. There are four main plot lines in the original Windows release that the player will have the chance to experience, one for each of the heroines in the story. Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. Some decisions can lead the game to end prematurely and offer an alternative ending to the plot. To view all plot lines in their entirety, the player will have to replay the game multiple times and choose different choices to further the plot to an alternate direction. In adult versions of the game, there are scenes depicting Tomoki and a given heroine having sex.
