In 'Whose Shadow Is That?', players step into the shoes of Eliza, a struggling art historian who has just uncovered a series of mysterious paintings in an abandoned gallery. Each painting depicts seemingly innocuous scenes that distort reality, casting bizarre, ominous shadows across the canvas. As Eliza investigates the artist and the hidden truths behind each piece, she becomes ensnared in a labyrinth of psychological puzzles, where the line between art and madness blurs. Players must decipher cryptic clues, interact with a cast of eccentric characters, and confront their own past experiences to unveil the dark secrets that lurk within the shadows of the gallery.
