The Mechanics
A Self-Guided Historical Treasure Hunt
The gameplay mechanics of TimelineQuest are designed under the concept of a "Self-Guided Historical Treasure Hunt". Your phone becomes a time instrument: it reads where you stand, reveals what happened there, and challenges you to prove you understood it before the next door opens.
