The Alley is an indie adventure simulation game in which you find yourself trapped in an endless, labyrinthine alleyway on your way home from class. Armed with a supernatural detection bracelet given to you by your mudang grandmother, you must identify and photograph Aberrations signs of otherworldly phenomena while distinguishing them from ordinary Illusions, which only appear supernatural. Successfully detecting certain anomalies earns you keys that unlock the Chest of Truth, which reveals dark secrets and grants access to hidden areas where you will discover the truth behind these ghostly apparitions.
