About This Demo

  • An Adventure Through the Depths of Dreams

Subsomnia is a journey through the dream world, where a young protagonist must overcome countless challenges to reach the very origin of dreams.

No two dreams are ever the same. Thanks to its procedural core, every run generates different worlds with surreal atmospheres. Your mission is to traverse these dreamlands, interacting with shadow creatures and shattering the crystals that fuel them.

  • The Slingshot: Precision and Ingenuity

Your slingshot is more than just a weapon, it’s a tool to navigate the riddles of dream.

Dream Geometries: Master projectile physics and wall ricochets to hit impossible targets or trigger distant switches.

Physics Puzzles: Solve environmental challenges that demand intuition and aim, turning every puzzle room into an opportunity for massive rewards.

  • Magical Objects and Dream Worlds

Your path is guided by objects steeped in nostalgia and magic. Finding a teddy bear might transport you to the heart of an enchanted forest, while other artifacts open doors to worlds with unique themes and ever-changing challenges. What lies at the end of all dreams? Only the boldest dreamers will find out.
