The Diary is a 2D suspenseful narrative puzzle game that revolves around several distinct "diaries," including a journal full of life but full of doubts, two investigative notebooks written by different people, and the planner's diary, which will all be displayed before you.
By solving each page's puzzle, you will turn the pages and gradually gain insight into a heart-stopping missing case. From different perspectives, you will uncover the buried past behind the case.
· Open an unknown diary and search for its owner while solving puzzles
· Among 6 characters, whose perspective are you reading the diary from?
· With multiple reversals, the answer may be right in front of you or it may never appear
