Monster Ring and other Hotfixes :) (1.0.52)
This update adds some hotfixes: · BUGFIX: Monster Ring wasn't functional before - now it works :) It adds to the max monster count and doubles the monster spawn rate. This also makes it possible to spawn monsters in Creative Mode to get ectoplasm or slime. · BUGFIX: RNG (random number generation) fix for IsReactionValid, should make reaction rates more consistent regardless of position · BUGFIX…
This build adds a number of bugfixes. The biggest one is that random number generation (RNG) is revamped to prevent inconsistencies that were present before. RNG volumes are now generated in a way to give guarantees that they will visit the entire value range for any given position, and some other fixes with how the RNG functions were being called fix an issue where the call would only get a su…
This update adds Phosphoric Acid and some ways to create a variety of sodas and cola :) (making soda is going to be important for an upcoming Slime Ranching update) Apatite also now mines into 3 variants: Fluorapatite, Chlorapatite, and Hydroxylapatite, each of which can react with Sulfuric Acid to obtain Phosphoric Acid. The three types of mined apatite can also be blending with water to form…

Lasers, Mirrors, and Prisms! (1.0.43)
This update adds a bunch of things related to lasers! · Emerald, Sapphire, Amethyst, and Diamond Laser pixels are now craftable! · Mirror Pixels are craftable from Silver and Glass! They deflect lasers, and can be opened/closed using signals. Two Mirror Pixels on a 45 degree diagonal will deflect an incoming beam as if they are a 45 degree line. · Prism Pixels are craftable from Glass and Lead…
Here are a couple quick hotfixes while I'm working on some bigger updates: · QoL: delay resaving the *.universe file when the player restores an element so it doesn't create a pause - this is what was causing the freezing for some people when completing an element in the ship progression, so I wanted to get this in right away · QoL: changed the way spawning is suppressed by built pixels so that…

Hotfixes and Andesitic Lava Chemistry (1.0.40)
Today I did a bunch of bugfixes, and also made adjustments to lava! Andesitic Lava now cools into Sodium Aluminosilicate, and I added reactions for Sodium Aluminosilicate and its downstream products: Sodium Silicate, Sodium Aluminate, and Aluminum Hydroxide, to connect it into other parts of the reaction web. :) Bugfixes in this build: · BUGFIX: Rocket and Nuke Counters were not disappearing an…
Atomcraft is on sale for the week of the PvE Survival Crafting Fest!!! Here's an overview of Survival Mode for new players: SURVIVAL MODE OVERVIEW Survival Mode adds a lot of additional challenges to the core building/exploration-oriented mode, for example: · Slimes spawn on the surface and are more prevalent (more combat) · You need to eat regularly, and can eat raw pixels without having to wa…
A bunch of quality-of-life improvements in this build! 1.0.32: · Added "Show HUD" toggle on F6 · UPGRADE: Recharge Rate 4 added, to make Particle Accelerator beam easier to use · Added Credits Screen · Made the achievement for the best ending also trigger the “escaped the asteroid belt” ending · Moved the Sim Loader pixel to the first category of craftable pixels; it feels like it's better not…
This adds a few things, mostly related to the save system: · put in better containment for when errors occur on planet segments in the loading and saving processes · in situations where a planet segment didn't get saved properly, will load as empty instead of being filled with sand · BUGFIX: fixed a bug where not all active chunks would necessarily get marked to be saved · BUGFIX: made the "Sav…
We have big updates to the save system in this build! The new save system will save everything related to a particular world into a singular .universe file in the Worlds directory (currently about 120MB). It does atomic saves and maintains a list of 5 rolling backups, so it should be much easier to restore if something happens and should sync much more easily using Steam Cloud (also will help k…

Performance improvements, started adding videos to menus :) (1.0.29)
With this update I have mostly made some improvements to memory allocations and performance that should help to reduce stuttering for players who have been experiencing it. But also, I found out how to play video clips in Godot and started adding video previews to the crafting menu! The first three categories are about done - over the next couple days I will keep filling these out until we have…
Just a couple quick things today: · QoL: If something is already in your Material HUD Bar and you Middle-mouse-button it to select it, it'll just select the existing material slot instead of assigning a duplicate · QoL: Walk-Through-Walls Boots only operate when in Jetpack Hover Mode or when using the Jetpack if in Impulse Mode - this makes bases and platforms much more easily compatible with t…
Temperature Sensor pixels are now in the game! These should be handy for temperature regulation in machines. :) You can use Rotate and Program (as well as the Wrench) to adjust the settings. Possible values are 500K, 1000K, 1500K, and 2000K. When the Temperature Sensor pixel reaches that temperature or higher, it generates a signal, and turns off as soon as it drops below. Also today: · QoL: fi…

Balancer, Splitter, and Simulation Controls!
Some great updates today: the Balancer and Splitter are now added to the game! The Balancer takes in inputs from the left and the right in a perfectly alternating manner, and drops them below. Each time it takes an input from the left or the right it switches state, and it only advances when it actually receives an input, so you can use it to create perfect 50/50 mixtures of things. The Splitte…

Berry Bushes now plantable! And other hotfixes...
Berry bushes can now finally be planted using Berries :) They grow very quickly (will probably get some tuning in the future), so now you can create your Berry and Wine auto-farms! Other hotfixes: · BUGFIX: another attempt at making the jump/jetpack-impulse fully framerate independent; hopefully this works for everyone now :) · BUGFIX: fixed Rotation 'R' when using the Mega Multitool · BUGFIX:…
Here are some quick hotfixes and additions for Survival Mode! · Wire-blocks now allow materials to pass through vertically or horizontally, but block on diagonals - the diagonal passage was creating some confusing situations with ways that people commonly use wires, so I'm hoping that this is a good middle-ground · Added a V key to Vomit, which currently causes all of the materials in your stom…

Survival Mode is now in the game! I know what you're thinking - there already was a Survival Mode! Well, that mode is now Normal Mode, and we have a NEW mode called Survival Mode which adds a lot of additional challenges, for example: · Slimes spawn on the surface and are more prevalent (more combat) · You need to eat regularly, and can eat raw pixels without having to wait to assemble them int…

Multitool, Upgrade Pinning, and more!!! (1.0.15)
The Multitool is now in the game! This tool, available after the Crowbar, combines the functions of Hammer and Crowbar into one for extra-fast building!

Just a quick update to add a long-requested feature: Toggleable Pumps! These give you a lot more control over how you move materials between chambers. :) You could even hook them up to timers and sensors to make more precise machines.

This build adds a LOT of hotfixes and quality-of-life improvements! · BUGFIX: gases no longer condense when in space (only when in the atmosphere) · BUGFIX: fixed a logic issue with how the maxed-all-friendships achievement was awarded in the demo, where you could trigger it early by accessing full-game npcs (now only responds to the demo npc friendship levels) · BUGFIX: the new Help and Feedba…

The cows and chickens will now properly respawn where you're placed them, so you can start creating automatic farms. :) They still sometimes fall through single width floors though, so I'd recommend making them at least double-width for now, until I have a chance to revisit collision.

READ BEFORE LAUNCHING PLEASE! - Steam Cloud is now active and linked!
Steam Cloud is now set up for the full game, and is linked to the same save path as the demo. This should seamlessly carry over people's saves from the demo, however - if you have local data for the full game that would be overwritten by a previous demo, you should probably make a copy of your save directory before playing, to restore your files after Steam does the first cloud sync. You can al…

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 Crys…

This update adds some new things related to cows! Cows now actually eat grass. After eating 6 pixels of grass (max 2 per bite), they will poop. The Cow manure reacts with Soil to create Loam. There is also a new craftable Cowbell pixel in the Extra pixels category. The Cowbell is a signal-activatable pixel that causes any nearby Cows to produce Milk if they are ready (there is a one minute cool…
