Eastern Mind: The Lost Souls of Tong Nou is an inventory-based point-and-click adventure game.
The player taking the role of Rin, is a young man who has lost his soul. With a temporary soul from a friend that will keep Rin alive for 49 hours, Rin travels to the living island of Tong Nou to recover his soul. Tong Nou is a strange, living island, that takes the shape of a giant green head (actually the one of the designers Osamu Sato).
There, Rin will visit the five lands that were created when the universe was born: the Lands of Time, Desire, Dreaming, Life, and the Central Mountain of Tong Nou. Rin will revisit these lands often during the game. To solve the quest, the player may even have to die and reincarnate nine times, causing the player to play the game from the perspective of nine different characters. To complete the game, the player has to accomplish the goals of each character.
