In 'Hello, Dark Passenger', you play as Casey, a struggling artist living in a bustling metropole. Frustrated and feeling invisible, Casey stumbles upon a mysterious app that allows them to communicate with their own shadow self—a dark, sarcastic version of themselves that thrives on chaos and mischief. Together, you embark on a series of interactive missions that challenge the status quo of your mundane life. As you navigate through both literal and metaphorical shadows, confronting quirky characters and twisted dilemmas, each choice leads you down increasingly dark and surreal paths. Will you succumb to the temptation of your 'dark passenger' or rise above it? The fate of your reality is in your hands, and every decision has consequences.
