NOOK: Uncharted Journey, a classic choose your own adventure game, starts when Ergin, who survived the falling avalanche during a mountain climbing, reaches you for help.
While supporting Ergin in order to survive, you will encounter a secret hidden by the mountain he climbs. Your responses to messages you will receive from Ergin throughout the game will also be decisive in your relationship with him and will affect the end of the story. You will not only help Ergin survive, but also help him solve the moral dilemmas he fell into.
The choices you will encounter in NOOK are not only about choosing one of two ways or one of three items. Sometimes you will have to persuade Ergin, who is a living character as much as possible and has his own values, for your choices.
NOOK, a text-based game, is also supported with visual and audio materials, making the player feel the world of the story. If you encounter choices that result in the character's death in the middle of the game, you will return to pre-determined fixed points and have the opportunity to change your choice. However, since NOOK follows your behavior towards the characters since your first choice, some of your decisions will be irreversible.
