X-Note is an otome themed visual novel for PC, Mac and Linux. It is the story of a girl named Essi, a young psychic.
10 years before the beginning of X-Note, Essi’s mother died in a car accident. The circumstances were suspicious and the accident was ruled a murder, but the police were never able to find her mother’s killer. Two years ago, Essi realized that a necklace left to her by her mother is actually a USB flash drive containing one password protected folder titled X-Note. Essi is certain that the contents of X-Note will make clear the circumstances surrounding her mother’s death. When Essi is recruited by Yuon to investigate another murder at the Xen Institute, a school her mother helped found, she begins a journey to discover the history of the school, its founders, and a mysterious boy named X.
The gameplay in X-Note is comprised of two main elements: reading text and choosing dialog or movement options, and minigames. The visual novel elements are fairly typical and involve the player making basic decisions about dialog options, which characters to spend time with, and which locations to visit. By the end of the game, should the player have chosen the correct options, Essi will become romantically involved with one of the three main characters.
There are three types of minigames in X-Note, each corresponding to one aspect of Essi's psychic training. In the Psychokinesis training minigame, the player is presented with a gauge that is fluctuating quickly and must click a button when the gauge is full. Clairvoyance training involves the rapid memorization and recall of a series of symbols. The last training minigame, telepathy, involves matching a series of rapidly changing symbols.
