The Light That Binds Us

The Light That Binds Us is a 3D puzzle-narrative adventure set in Diyu, the transitional underworld of Chinese mythology. After Yuè, the daughter of a local lord in Tang-era China, dies in the flames of political war, she reunites with her faithful celestial guardian dog, Yún. Together, they travel through Diyu, uncovering forgotten memories, facing spiritual trials and confronting the destiny shaped for Yuè before her death.

Diyu

Diyu takes the form of the lives of those who pass through it: their joys, sorrows, memories and even the circumstances of their deaths are etched into its walls. You explore misty caves, mountain ranges, ancient temple complexes and dense forests inspired by historical structures of the era. Monumental statues, hidden wall frescoes and story-rich collectibles—including the Damaged Doll, Bloodstained Dao and Custom Tea Set—gradually reveal the tragedy behind Yuè’s fate.

Shape shadows

Inspired by Chinese shadow puppetry, the game makes shadows into physical platforms. By projecting light across the environment, you turn empty spaces into paths you can walk, climb and build on. To solve puzzles, you adjust the light source’s position and distance, the projection angle and the shape of the object casting the shadow.

Work with Yún

Yún is both Yuè’s companion and a living light source. You can command him independently to solve environmental puzzles that require precise coordination between the two characters. Together, you activate ancient stone artifacts, ignite dormant light plinths and amplify receptacles to manipulate complex geometry; your collaboration determines your progress through Diyu.

A changing score

The dynamic score combines Western orchestral composition with live-recorded traditional Chinese instruments, including the Erhu played by Eliott Tordo and the Xiao flute played by Josh Plotner, alongside vocals by Aeralie Brighton. The music shifts in real time to match your exploration and emotional journey.
