Toggleable Pumps! :)

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.

fixedBUGFIX: Brass and Barite now have weights
fixedBUGFIX: Crowbar should now break any build pixel at any hardness; walls generated for the Labs biome are now Ancient Corundum Walls which don't count as "built" pixels for the sake of the Crowbar, to maintain progression
addedQOL: Added the Ctrl modifier to Blueprint building - when holding it, it will just build as much as possible of the blueprint from your current materials (this is a QOL a lot of people have asked for)
changedBALANCE: Reduced Ceramic's Hardness to 4 so it can be drilled with the Iron Drill - this is to prevent people from getting trapped in their own Ceramic Walls early in gameplay. The Crowbar could already decraft these, but now the Drill can mine it as well.
changedPERFORMANCE: improved the algorithm for heat conductance to make it run faster (shouldn't affect heat behavior yet, just increase efficiency of code)

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.

Some additional things in this build:

  • BUGFIX: Brass and Barite now have weights

  • BUGFIX: Crowbar should now break any build pixel at any hardness; walls generated for the Labs biome are now Ancient Corundum Walls which don't count as "built" pixels for the sake of the Crowbar, to maintain progression

  • QOL: Avatar now mostly fades out when the cursor gets very close to it, to aid in building

  • QOLAdded the Ctrl modifier to Blueprint building - when holding it, it will just build as much as possible of the blueprint from your current materials (this is a QOL a lot of people have asked for)
  • BALANCEReduced Ceramic's Hardness to 4 so it can be drilled with the Iron Drill - this is to prevent people from getting trapped in their own Ceramic Walls early in gameplay. The Crowbar could already decraft these, but now the Drill can mine it as well.
  • PERFORMANCEimproved the algorithm for heat conductance to make it run faster (shouldn't affect heat behavior yet, just increase efficiency of code)

Extra addition:

I added Bubblers to the game - this is a pixel that swaps the cells above and below it when a gas pixel is underneath - you can use this to bubble gases through liquids and solids! :)

EXTRA extra addition (Aug-09-2026 Sunday morning):

I fixed a bug that was causing radioactive materials to not properly appear in the nuclear blast. I also rolled back a heat conductance change yesterday that requires some additional material rebalance, and should be part of a future overall heat system update.

This should enable some new machines over the weekend! I'm working on more new pixels and quality-of-life updates, check out the Discord community for the most up-to-date info!
