Echoes of the Past is an interactive fiction game where the player assumes the role of a time traveler who can communicate with different historical figures. The game takes place during a time-travel convention where you must convince other time travelers to help you save the world by identifying specific times and places where the timeline was altered. Using speech and music generated by Bark, you must navigate conversations with a variety of figures from history, such as Leonardo da Vinci, Napoleon Bonaparte, and Alice Paul, and convince them to help you in your quest.
