About The Long Mine
Dig Deeper
The Long Mine is a physics-based mining game with incremental progression. Mine your own path through the rocks and discover new areas. The deeper you go, the harder it becomes to keep going.
Unique Loadout
Choose equipment that changes how you mine, move and explore. Some give simple stat boosts, while others let you do things you couldn't do before.
But you can't equip everything at once. Equipment space is limited, so you have to think and choose what works best for you. Combine different effects, create your own build and unlock more equipment space as you progress.
Curses
Find or buy essence and curse stones, then use them to roll random Curses onto the stones.
Some Curses make you stronger, others have drawbacks, and some completely change how you play.
You decide which cursed stones to equip. You don't have to use every Curse you roll, so choose the ones that work best with your build.
The rolls are random. What you do with them is up to you.
Exploration
Every new area has its own layout, obstacles and ways to get through.
Use a rope to carefully climb down, find a safer path, or just yeet yourself down the slope and hope for the best.
The deeper you go, the darker and quieter the mine becomes. You might start wondering, "Surely the developer isn't going to scare me on purpose... right?"
Find the Source
Miners say there's something deep beneath the island.
Some hear strange sounds. Others find signs that someone has already been there. And some even claim they saw something moving in the darkness.
The deeper you go, the harder it becomes to believe the mine is actually empty.
