About the Game
Welcome to Coal LLC, your friendly-everyday-evil-coal-mining-corporation.
With only a shoddy pickaxe to start, you must hire and promote employees, upgrade equipment and dig deep below the earth to fill your coal quota each day. Or else.
Feed the factories.
The underground world magically refreshes each day, so you must race to mine as much of it and as deeply as you can before nightfall. Using some very exciting and hyper-realistic methods for doing so. Your world might deteriorate as you grow, however.
Hire BILLIONS of employees.
You heard that right. Hire and promote employees into specialised roles in your organisation, each type having exciting and game-changing bonuses and equipment. Grow your organisation into hundreds, thousands, millions and even billions of miners willing to go out and bring back coal for the cause.
Don't be afraid of the consequences.
Many different maps, professions and tools means endless ways of growing your operation. Do you have what it takes to grow the greatest coal mining corporation of all time?

Steam Patch Notes
Official update history
- Very big change to how the passive effects are rolled for in chests. Passive Effect choices from chests now have a significantly higher chance of matching your current build. Should be particularly noticeable for classes with a lot of weapons available to use.
- Added a new Hard Mode Modifier: No Chests.
- Ultimate Destructor now has access to the new boxing gloves and roundhouse kicks items.
- Orbs are now a bit cheaper to purchase.
- Minor performance improvements/bug fixes.
Enjoy!

- Passives for the new weapons should now properly appear for the ultimate destructor class
- Items will no longer fall through to infinity (occasionally happened with a certain combination of small chunk size setting and using nukes as demolitionist)
- Fixed bug with shifting ground not saving between sessions.
- Jets can now be turned off with right-click (and placed as usual with left-click)
- Added lightning pickaxe shock effect sound to the lightning pickaxe buzz sound slider (originally it was only the background idle buzz that was affected)
- Fixed SFX channels for new weapons.
- Fixed bug with Firestarter Chest Passive choices containing a <null>
- Fixed a reference to the old name of the Combined Arms profession.
- Removed debug label on collectors that was left visible in the last update.
- Fixed most of the major bugs with various counts in the game. You should no longer feel limited to ~1e21 coal count.
- Collectors should do their jobs better.
- Item drop numbers in the later levels have been increased to match their appropriate levels.
Finally - I appreciate your patience regarding the bugs in the endgame update. The code is spaghetti, and lots of sneaky int()'s were lying around messing things up. Hopefully a large majority of these have been solved now.
Thanks,

- Fixed bugs where employees get stuck and stop mining when their movement speed gets too high.
- Added sound to the InfiniLadder when placed.
- Employer miner speed passive effect now affects their gravitational fields. Miners will now fall down quicker under the effect, and therefore should mine down quicker.
- Added adjustable sliders for the passive effects: player sprint speed, jump velocity and climb speed.
- Added a new item - the InfiniLadder - a placeable ladder which automatically extends all the way down and all the way up until it collides with a tile. Combine with player climb speed upgrades to create instant elevators for yourself wherever you are.
- Fixed bug where pickaxe speed drops completely at certain high values.
- Fixed bug on win game/lose game screens and when storing record data that was still limiting the values to integers.
- Fixed bug where the incorrect number of collectors would sometimes be visible.
