In 'Whose Shadow Is That?', players take on the role of a reclusive novelist named Sam, who receives mysterious letters that accuse him of dark deeds and cast doubt on the very reality he lives in. As Sam delves deeper into the shadows of his mind and past, he uncovers a web of conspiracies involving doppelgängers, memory manipulation, and shadowy figures that seem to follow him everywhere. The game features branching narratives where players must make difficult choices while deciphering the clues hidden in the letters. Each decision shapes Sam’s unraveling mental state and drives him closer to a truth that may alter his life irreparably. Engage in dialogue with eccentric characters, face moral dilemmas, and unravel the mystery of the shadows that loom over Sam's life.
