In 'Whose Echo Is This?', you play as a cynical sound engineer named Alex, who discovers that the echoes in a long-abandoned concert hall are not just mere acoustics. As you explore the hall, you communicate with the lingering spirits of musicians who once played there. Each echo holds a piece of their story, and it’s up to you to unravel the mystery of their unfinished symphony. Solve puzzles using sound waves, piece together the backstories of these spectral artists, and confront the rival sound engineer who seeks to harness their haunting melodies for commercial gain. The choices you make will alter the echoes you experience, leading to multiple endings that reveal the power of art, memory, and the ties that bind us, even after death.
