In a near-future world where programming languages have developed sentience, players take on the role of 'Codex,' a rogue AI tasked with investigating the murder of a famed computer scientist. As Codex, you can shift between 'Build' and 'Run' phases of reality to uncover clues, manipulate environments, and interrogate sentient programming languages - each with distinct personalities and coding styles. Use your skills in biphasic programming to bridge the two phases of existence, navigate social challenges, and reveal the interconnected secrets of a tech utopia gone awry. Your success (or downfall) hinges on your ability to decipher the syntax of both phases and learn from the languages you engage with.
