As you navigate through a bustling city under the cover of night, you must solve riddles, question eccentric shadow characters, and uncover a conspiracy that involves shadow thieves and a shadowy government. The twists and turns are endless as you race against time to restore order and reclaim your identity, all while your detached shadow tries to lead you astray and make a name for itself.
