In 'Haunting Harmonies', players step into the shoes of an unknown composer trapped in a seemingly abandoned opera house. As you explore the dimly lit corridors and hauntingly beautiful stages, you unravel the secrets of the ghosts who once breathed life into the music. The main mechanic revolves around using melodies to manipulate the spectral spirits, solving riddles that unlock hidden passages, and piecing together the tragic fates of the legendary performers. Can you create a symphony powerful enough to free their tormented souls—or will you become another echo in the opera's cursed halls?
