About Drill Deep

You expected to meet your end in the noose when Her Majesty commuted your death sentence to something much worse. Given your distinguished expertise in excavation, you are hereby assigned to oversee operations at a new imperial mining facility.

A coalpunk Lovecraftian idler wrapped in pixelart grime and coal dust. Horror doesn't chase you: you're walking towards it, one block at a time, and you won't notice until you're already lost. Your task is simple: dig.

You will manage the dig and expand the surface base. You will optimize, automate, and upgrade. The empire expects results: coal, ore, or whatever else the earth is hiding down there.

The task seems familiar: dig a block, gather a resource, build something and dig deeper. The surface camp grows, smokestacks rise, progress charts tick upward. It’s almost cozy out there. Definitely better than the gallows

But the earth hides all sorts of things.

As you descend, the rock gets older and your finds get weirder. At first it's curious: unusual formations, oddly-shaped fossils, inscriptions in unknown language. Your workers don't comment on them. Neither do you, at first.

And then you stop sleeping well. The Mine is calling you.

Key Features:

  • Idle-clicker with real depth - a simple loop that gradually unfolds into a layered upgrade and building system with meaningful choices
  • Surface base building - construct and expand your industrial camp to unearth what lies below
  • Buried lore - every unearthed object and broken block hints at a world that existed long before humanity came to existence. Some of it bites back.
  • Incremental dread - horror that scales with progression. The deeper you dig, the more reality strains at the seams
  • Horror for non-horror players - no jump scares, no punishment for exploring. The dread just waits for you to reach the bottom
  • Roguelite mode - high replayability with procedural generation for those who want to return to the dark
