About This Demo

Step into a haunting Metroidvania where reality bends and memories fracture.
You awaken without a name, guided only by whispers echoing through distorted landscapes. Each biome is more than a setting—it is a reflection of fear, paranoia, and forgotten trauma. As you venture deeper, you’ll face enemies that embody inner demons and bosses shaped by shadows of the past.

  • Explore surreal biomes that twist and distort with your state of mind.

  • Battle grotesque bosses, each representing a piece of buried memory.

  • Uncover fragments of your identity and piece together who you really are.

  • Meet enigmatic NPCs who may help you... or deceive you.

Every victory brings you closer to clarity, but also deeper into the labyrinth of your own mind. The world itself shifts as your sanity falters, turning exploration into both discovery and descent.

This is not just survival.
It is a confrontation with yourself... and the truth you may not want to find.
