🪨 Enter a quiet world beneath the rock. 🔦

Explore ten fictional cave stages, from a pale limestone gallery to a vast underground cathedral. Map the passages you discover, investigate dead ends, and bring your discoveries safely back to the surface.

🧗 Core Mechanics & Obstacles

Survival and navigation depend on careful planning and route management.

• Rope Rigging: Steep shafts require a rope rigged at the top. Descend, leave your rope in place, and climb it on your return. (Warning: An unrigged shaft cannot be climbed from below!)
• Dynamic Environments:
  • Stage 07: Navigate a complex through-cave.
  • Stage 09: Beware of rising water that will close off the low return route.
  • Stage 10: Complete your grand expedition with a challenging journey back to the original entrance.

🎮 How to Play
