About the Game
Atomcraft is a game where you can pick up and place every pixel of the environment. Pixels react to whatever is around them, and you can build vessels and machines to make reactions happen.
Upgrade your drill and your tools to dig deeper and deeper into the planet in search of better materials!
Smelt ore and perform chemical reactions!
Build machines to do chemistry and extract elements!
and repair your spaceship piece by piece!
Every element on the periodic table will exist somewhere on the planet, although extracting them from their ores may require some creativity!
You can also craft mechanical pixels, such as:
conveyor belts
trapdoors
heating and cooling elements
wiring for signal-based machines
buttons, switches, and sensors
and even logic gates!
Advanced materials like nitroglycerin require careful construction of reaction machines to craft them without the materials exploding!
Delve deeper and deeper through the layers of the planet until you discover every material on the periodic table, repair the systems of your crashed ship, and possibly uncover the fate of this mysterious world!

A couple new things in this update:
Walk-Through-Walls Boots were an idea from the Discord community this weekend - equipping them lets you fly through any and all built pixels: walls, conveyor belts, machinery, etc. They require Uranium and Ectoplasm and are intended to be in the last quarter of the game as an improvement to Allow Player pixels. Convenient!

Ruby can now be built into Ruby Crystal pixels that stay in place, so you can build structures out of Ruby. This also makes it easier to place Ruby Crystal pixels in the middle of a forge and expose it to Molten Alumina and Molten Chromium, which will grow additional Ruby Crystal pixels that you can then mine. (remember: you can mine a specific material by holding Ctrl while you drill!)

The F1 Help Screen now has a rotation of tips and tricks to help surface a lot of the helpful hotkeys and controls that tend to go unnoticed until someone mentions them. :)
Other additions:
Ctrl + Alt with the Hand will now pick up everything EXCEPT the hovered pixel :)
Ctrl + Mousewheel will now zoom the camera in and out (in addition to the plus/minus defaults)
There is a language page in the Settings Window for a duplicate way to set localization; some people were still not seeing the localization button in the corner of the front-end and in-game menu. Those are still there, but now the Settings Window, where those people were looking, also has a way to do the same thing.
READABILITY: added a cause-of-death message for radiation death, as it was confusing some people when they died to it in the underworld
BUGFIX: Sim Loader pixel now counts as Mechanical
BUGFIX: some Mechanical pixels had an incorrect setting preventing them from being crowbarred - this is now fixed
MISC: if a reaction has a required temperature of 0, don't show it in the visual (since it doesn't actually affect anything but was confusing)
MISC: Burning Charcoal now blends into Carbon for consistency
MISC: Made the Handbook icon in the F1 menu look like the Handbook instead of the Guide Tab icon
I think that's everything new for now - we'll have some more cool things coming in the next day or two. Keep bringing your suggestions and feedback in the Discord, and see you soon!
And by the way, thank you to everyone reviewing the game!

Here is another set of hotfixes and updates:
CONTENT: added Grass Seed (mines from Grass, can be planted on Dirt or Loam)
REACTIONS: alumina reduction works better with molten alumina now (should be much less finicky)
REACTIONS: made an adjustment so Vanadium Dioxide can react with Molten Aluminum (which makes more sense with the heat range) - should make Vanadium extraction easier
REACTIONS: added the Gravel version of Sulfuric Acid & Water dissolving Granite
QUALITY-OF-LIFE: added Reset to Defaults button to the Settings->Control Bindings list
QUALITY-OF-LIFE: added an Unstuck button (backslash by default) that will pop the player out of stuck spaces
QUALITY-OF-LIFE: When updating the Guide Tab, Inventory Tab, or Spaceship Inventory searches, always refresh the scrollview to the top
QUALITY-OF-LIFE: default to showing Output reactions in the Guide Tab whenever we select a new material
BUGFIX: highlights for the Crowbar and Wrench were using the dotted-line setting from the Hammer; this is now fixed
BUGFIX: Encumbrance warning no longer appears when in Creative Mode
BUGFIX: Creative Mode no longer allows damage to the player (or air loss)
BUGFIX: Creative Mode now has free upgrades!
BUGFIX: made Blender pixel Hardness 0 so we can always Crowbar it
BUGFIX: laser width could previously be changed using Alt+Mousewheel hotkey even if you didn't have the upgrade yet - this is now fixed
BUGFIX: adjusted weight of gasoline and other oil-derived vapors to make them heavier than carbon dioxide
MISC: removed duplicate materials: Molten Glass (which is already Molten Silica) and Corundum Gravel (which is equivalent to Alumina); mining Corundum Walls will now give Alumina, and Alumina can build into Corundum Walls
Stay tuned for more info on the content plans for the game! Last night on the stream we talked about a lot of ideas for the first major content update, that will coincide with the Autumn Sale - going to do a post about this soon! :)
Hey everyone, I did a bunch of quick fixes and quality-of-life improvements today:
BUGFIX: fixed achievements in the full game so they trigger correctly
BUGFIX: fixed a bug with Cooling Pixels where they could freeze materials next to them in place
BUGFIX: no longer give achievements when in Creative Mode
BUGFIX: added a backup condition where if the device profile is corrupted we create a default one instead of hanging
BUGFIX: air cooling was producing sand sometimes - this was broken reference to liquid oxygen which is now fixed
BUGFIX: fixed some material rendering issues in the spaceship inventory
BUGFIX: when the Hammer is building, only make a sound if you had material and building actually occurred
BUGFIX: in the Spaceship Inventory, only allow pasting non-negative numbers into the field
BUGFIX: when ending a session and exiting to menu, reset weather
Quality-of-Life: mute single-drip sounds by default
Quality-of-Life: put the Solar Panel into the laser pixel set so you don't unlock the set and not have a source of grid power
Quality-of-Life: when opening the Spaceship Inventory transfer dialog, make sure the cursor is at the end of the existing number in the field
Quality-of-Life: added phase-of-matter icons to the Spaceship Inventory list
Quality-of-Life: added phase-of-matter to the hovered pixel tooltip
We'll have some more updates tomorrow before the weekend! See you Friday! :)

This update adds the ability to track materials - when you click the eye button in the guide, the material will be added to the pinned list, and sparkling effects will play wherever the material is. This effect shows through fog-of-war, and can make it easier to identify and locate ore deposits.
Other things in this update:
Reactions: added Hydrogen Bromide + H2O to make Hydrobromic Acid
Reactions: added reactions to reclaim Manganese from Manganese(II) Oxide, Manganese(II) Chloride, and Manganese(II) Sulfate (fixing some dead-end materials)
Quality-of-Life: save/restore whether to show if a material is in Inventory+Ship
Quality-of-Life: allow middle-mouse-clicking the pinned recipe ingredients to assign them to the current selected slot
BUGFIX: NPCs no longer duplicate when exiting/entering a session through the menu
BUGFIX: fixed the behavior of the upgrade tooltip freezing when pressing Shift
BUGFIX: Heat Insulator pixel is much better at insulating heat now
BUGFIX: don't toggle Lock Slot when an edit field / the console is active
MISC: cleaned up materials and reactions to remove old stuff that is no longer used
More updates coming soon!
This adds 4 more languages: Hungarian, Swedish, Vietnamese, and Indonesian! :)
[img src="{STEAM_CLAN_IMAGE}/45610368/cac57161ab6d2c6bd40580869aa7291fb614ff30.png"]
Also:
BUGFIX: in Creative Mode, made sure encumbrance isn't a thing
BUGFIX: Pipette mode (holding shift to pick up a single pixel) no longer accidentally does a normal grab if you miss the pixel and are hovering empty space
BUGFIX: Price on the Rocket tooltip now shows up consistently
BUGFIX: Tried an export setting that may improve word-wrap in Chinese/Japanese languages
Quality-of-Life: if the current HUD material is locked, we now see its name to the right of the material slots
MISC: Added some hardening and diagnostics around saving/loading the world to see if it fixes the occasional error where world segments get turned into sand
More updates coming soon!
This update adds a couple quality-of-life improvements that have been requested:
[img src="{STEAM_CLAN_IMAGE}/45610368/d017558ae0c0d97869881af16ba8f4e2eec602e4.png"]
Added Lock Functionality for Material Slots - if you press 'L' when hovering a slot, a lock will toggle on it - this keeps the slot tied to that material identity even if you empty it, so you don't accidentally change your slot assignments around.
- If you are not hovering a slot, 'L' will toggle lock on whatever the current selected slot is.
- The tooltip when hovering a slot will tell you when it is locked.
- Lock status is saved/restored in the savegame
Added Ctrl+Mousewheel & Ctrl+Shift+Mousewheel as shortcuts for changing rows (in Toolbar and Material Bar, if you have the multi-row upgrades)
If you hold Specific Material hotkey (Ctrl by default) over empty space, it will use whatever is in the current material bar slot
BUGFIX: added release-focus to the row-select buttons for the toolbar and material bar so they don't get retriggered by keys after you press them
More updates coming soon!
[img src="{STEAM_CLAN_IMAGE}/45610368/f45d661d01dbb318b90c1c7b590027b32c197744.png"]
This adds one of the most-requested upgrades: the Material Belt lets you have 10 rows of material shortcuts on the bottom of the screen! Now you can have a lot more control over the selections of materials you have available!
This upgrade requires Molybdenum, so you should be able to get it in the second underground biome.
Also, this update adds 3 more languages: Ukrainian, Italian, and Czech!
And the following additional things:
Made the Steel Alloy reaction not increase the amount of Iron in the world (consumes Carbon, but that is reclaimable)
Added a new room type for the lower level of the limestone caves that contains Cobaltite, to reduce the probability of not finding it
Increased the power output of the Turbine and Solar Panel pixels
Quality-of-Life: doubled the Ruby drop-rate from Granite
BUGFIX: Diamond now builds into Diamond Wall (not Diamond Deposit), which can be crowbarred
BUGFIX: prevented buying a recipe or a tool-bearing upgrade when the inventory is completely full
BUGFIX: prevented empty tooltip appearing over undiscovered map rooms when searching for materials in the World Map tab
Misc: added a texture for lava so it stands out visually in the lava caves
More stuff coming soon! :)
[img src="{STEAM_CLAN_IMAGE}/45610368/03f8ef19d2b8fd4aebafd226eeaac7547d6ff96a.png"]
Added Thai Language in this update! :)
Also:
QoL: save/restore settings for the Hammer, Crowbar, and Wrench :)
QoL: added highlight effects on toolbox slots (highlight the slot something can be placed in, better feeling of reactivity)
BUGFIX: rendering errors with some materials in UI contexts are fixed now
BUGFIX: Bowl of Coal shouldn't heal non-Fireguy anymore
More coming soon!
Here are some more fixes! :)
Quality-of-life: made Alumina reduction easier
BUGFIX: rebalanced Potassium Oxide + Sulfuric Acid
BUGFIX: fixed balance of Cesium Carbonate + Hydrochloric Acid
BUGFIX: non-match materials can now fall down a diagonal slope of filter pixels
BUGFIX: filters no longer stop horizontal movement (conveyors can push things through)
MISC: allow building walls using Diamond
More quality of life and other fixes coming soon!
People have requested this multiple times, and it's finally in: the worldmap can be zoomed and panned around (either with scrollbars or click and drag)
[img src="{STEAM_CLAN_IMAGE}/45610368/91ab14b039f524998f2da1b4848f6c9e579ad950.png"]
Also: fixed an issue with the demo achievement medals so they swing on the correct pivot points now :D
Some big updates coming this week, stay tuned!
I've been grinding on performance improvements all day and I think the game is now about 20-30 fps improved over where it started this week.
Even running a debug build through Godot it's pretty smooth / at 60 most of the time unless I max the sim area.
And I think there are probably additional improvements I can still make - this bodes pretty well for possible future additions to the simulation...
Other misc:
BUGFIX: fixed MENU_SETTINGS_LABEL_CONTROLS_ROTATE string that was missing from localization
BUGFIX: fixed IsBuilt flag (crowbar destructibility) on some variants of placed Heating Element
More coming soon!
This build is to add some performance improvements I worked on today that got back about 15+ extra frames per second :)
Also:
reduced threshold of when falling-material sounds happens so it isn't as annoying
BUGFIX: fixed an issue with the pixel lighting drop-off having been disabled in an earlier build
More performance improvements coming soon!
