In a shadowy city governed by enigmatic forces, players take on the role of a talented heart thief named Echo. Instead of stealing valuables, Echo swaps the hearts of various influential citizens—each heart holding not just the essence of the person but also high-stakes secrets that can change the city forever. As Echo, you must navigate a web of intrigue while solving puzzles, making moral choices, and crafting alliances with the unique characters driven by their heart's desires. Your ultimate goal? Unravel the truth behind a conspiracy that could rewrite fate itself, all while keeping a playful repartee with your quirky sidekick, a sentient heart-shaped artifact named Thump, who has opinions on love, fate, and snack breaks.
