Coal LLC News & Patch Notes

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! Bye Bye Ocean

Two new weapons: Boxing gloves and Roundhouse Kicks.
- Boxing Gloves: Powerful and quick, but can only attack adjacent rocks in four directions (up, down, left and right). Super precise but might be difficult to build yourself a path out. Has both speed and damage passive effect upgrades.
- Roundhouse Kicks: Begins as a weaker battle-axe. However, it continues to kick even when using another weapon. It also has both spin speed and damage passive effect upgrades (and yes... both are infinitely scaling).
Three new professions: the Martial Artist, the Shotgunner, and the Generalist+
- Martial Artist: Dual-wield the two new weapons, your roundhouse kicks and your boxing gloves, to MMA your way to the centre of the Earth.
- Shotgunner: Probably the biggest challenge so far. Can only use shotguns. But no platforms or ladders... or jetpacks... or wings... or hoverboards... or jump passive effect upgrades... or recoil passive effect upgrades... or employees... Good luck :)
- Generalist+: A continuation of the Generalist - has access to use all the new toys from the latest updates as well as everything else.
Some performance improvements, including improving how the sparks are generated by pickaxe strikes (may be noticeable at high pickaxe strike rates).

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 own volume slider for new jet weapon. - 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 - Fixed a reference to the old name of the Combined Arms profession.

What's New

Added three new professions to the game: Combined Arms, the Orbist, and the Ultimate Destructor.
Our new professions have three brand new weapons to use -> Tanks, Jets, and Orbs.
These also have their own passive effects to collect!
Added new bonus upgrades - you can now pay a pretty penny to remove the top layers of the world and shift layers closer to your spawn. No longer will you have to mine through an empire of dirt just to get to your favourite layer!

Other Changes

Electric Pickaxes now have a limited spread. I know... boo... but at least it might stop crashing the game on Coal-only mode (thanks Dex!)
Passive Selection might feel slightly more balanced.
Optimised some gun effects which will prevent unnecessary lag when using e.g. the minigun.
Some other small optimisations.

As always, let me know if you encounter any new bugs or anything is not working properly! I will try to patch it quick :)

Much love,

Bye Bye Ocean

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, Bye Bye Ocean

Applied passive speed bug fix to electric pickaxes too.

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.

Get ready for a HUGE endgame update (plus a few other nice things):

Most integers have been switched to floats, so max values of everything have increased from ~1e+18 to ~1e+308.
Two new professions: Assassin and Firestarter. Assassin will be immediately unlocked as long as you’ve beaten the internship.
Added four new tiers to every weapon, and four new extremely valuable gems to find deep underground.
There are now four more layers. Good luck getting through the final one!
Flamethrowers and Poison Guns now follow the standard shoddy -> copper -> etc upgrade path like other weapons.
All layers now have their own chests. Beyond the red layer, the chests only drop passive effect bonuses.
Added three more inventory stack upgrades.
Employee miners who have the AOE buff (barbarians) will now see the AOE buff scale with their passive effect miner damage.
You can now reduce your employee entity limit down to 50 to help with late game lag.
Player and employee fire/poison damage now properly affected by the relevant passive effects.

Thank you to all 50,000 of you who purchased Coal LLC! Big thank you to my Playtesters for helping it to become the best it could be, and thank you to the YouTubers and Streamers who shared my silly mining game with their audiences.

Big things coming,

Bye Bye Ocean

Added the hoverboard. An expensive toy, but it allows you to move in any direction with WASD, as well as hover in place. The hoverboard has a "sprint" option (hold shift, or toggle in settings). Sprint hoverboard movement speed scales with player sprint speed passive effect.
Added Hard Mode No. 5: Only Clay. Inspired by YouTuber & Modder Jinks' video:

Save data should be a bit more robust, with added backups and a change of technical system. In theory it should now prevent data loss if the game crashes unexpectedly. If you have recently suffered lost save data prior to this update, please reach out to me via Discord or Email, and I can help to try and recover your progress.

Bug fixes regarding new trophy system. Trophies and awards should now be saving and displaying properly.

Added Hard Mode Modifiers (Challenge runs) - unlocked for each profession by winning a standard game as that profession.
- Right now there are four new challenge modes:
  - Coal is worthless - Coal sells for 0g.
  - Only Coal - No other resources are found underground.
  - No Bonus Cash - No bonus cash at the end of each day.
  - No time upgrades - You are stuck at only 100 seconds each day.
Added trophies to the professions and map selection screens, so you can now see which ones you have earned wins, true wins, and hard mode modifier awards for in standard mode.
Your pet dog now gets wings when you have wings. Two pairs for the price of one!
Added a separate volume bar for the dog’s barking.
Added a separate volume bar for the electric pickaxe’s background static sound.
Added profession/map/mode/modifer details to the win and game over screens.
Added more windowed mode setting options.
Bug fix - players should no longer get stuck in the ground when teleporting home.
Bug fix - players should no longer get stuck in an infinite loop talking to Patrick the Panda.

- There is now a unique in-game mouse cursor that can be toggled on in settings, which may be easier to keep track of if you wish to use it. - Your mouse cursor can now be locked to the window via a toggle in settings. - When using a controller in-game, the virtual cursor should now be locked to your screen. - Bug fix: NPCs should no longer give you the silent treatment when trying to hand in quests or talk to them.

Bug fix - Sometimes collectors would get distracted while trying to return coal to the stockpile when you blew the collector whistle. Those collectors have been dealt with.

Collectors should no longer randomly run away and never return.

Minor bug fix: Fixed keybinds remapping bug not saving between sessions for some keys. (Please note the game will still say v1.0.1 in-game once patched.)

- Vacuum cleaner now lets you directly deposit via it by interacting with it (Default Key E) - Mortar guns received a significant boost in their damage, with two new tiers of mortar guns now available. - Bombs received a decent buff to their damage, with a new tier of bombs for the red layer now available. Bugs - Fixed broken unlock professions achievements - Attempted to fix a bug with the tile map that is causing some users' games to crash. - Next item and previous item now correctly saves your choices when remapping the key binds.

- Added an auto-sprint toggle in settings under the “Controls” tab. So you can automatically sprint and hold shift to walk. - Various bug fixes.

Fixed bug where the destructor class accidentally picked up items into their inventory from chests.

Changed Keybind for dropping items to CTRL + Left Click, instead of Shift + Left Click. This is to prevent the player from accidentally dropping items while they are sprinting and using their items.

- Added one-click looting chests upgrade (no longer need to chase falling items when collecting chests!) - Added option for a random amount of cash from passive effect scrolls

Small Bug Fixes - Unlock map achievements should now work properly (and should be applied retroactively when you reach the map selection screen.) - Achievements that should not be given in peaceful mode are no longer being given in peaceful mode!
