NOTE: To access your saved body plans from before the update, right click the game in your steam library->manage->browse local files. Your old body plans will be in the body plans folder, unless you manually saved them to a different location. You can copy the files to the new body plan folder, which you can find by clicking the folder button in the save panel of the editor.

Feb 25 2025 Build, Primordials Demo

hotfix:
- Fixed combo cells not getting unlocked automatically when you load a body plan using them in sandbox mode
- Fixed Seeker cells sometimes resulting in an unbalanced net force on the creature
- Fixed combo cells having infinite capacitance
- Reenabled F9/F10 for sandbox only
- Added safeguards to prevent mind control feedback loops from breaking things
- When reserving memory fails it will now try again with a lower limit
- Fixed bosses sometimes being inaccessible
- Fixed combo cells in your saved creatures list showing up in the mutation menu
- Fixed the game crashing if a laser cell is deleted while active
- Made copying a creature's body plan when you possess it an option in the game settings
- Fixed tutorial area sometimes connecting to first biome
- Increased world size to avoid map generation from hitting the edge
- Made loading a body plan with F10 unlock the combo cells it uses
- Adjusted the default thermal properties of cells. The overall effect should be that cells heat up and cool down more slowly
- Made moving exterior cells cool down faster, up to twice as fast
- Fixed the health property of cell tables in the lua api returning maturity instead
- Removed the diminishing force from jet cells at high speeds, instead jet cells have diminishing returns from increased voltages
- Fixed sticky cells transfering to stick to walls when they are already attached to a cell

gameplay changes & features:
- Added original music by Phrakture (Nafeu Nasir). Additional music will be added throughout development
- Added a new main biome
- More creatures by Keith
- New cells: Laser cell, Mind control cell, Speedometer cell, Proximity detector cell, Always on cell, Always negative cell, Detach detector cell, Elastic cell
- Editor improvements
- Added a new panel to the editor which allows you to stash groups of cells, save and load body plans, view your undo history, and load the body plans of existing species. The "secret" F9/F10 buttons to save and load body plans are now disabled. To put your previously saved body plans into the save panel, you can click the bottom right button in the save panel to open the new body plan folder and move your previously saved body plans there
- Pressing control-S will save your current body plan
- Pressing control+A in the edit menu will select all cells
- Holding control while dragging selected cells will now duplicate the dragged cells
- Possessing creatures in sandbox mode now automatically switches loads their body plan as well. You can access your previous body plan using the history tab of the new panel
- Amplifying cells have been renamed to Lightning cells
- Acid cell cost increased from 10 to 12, and have been made about half as common
- You are now less likely to hit yourself with lightning while moving quickly
- Sticky cells now lose stickiness based on pulling force, rather than loosing stickiness at a constant rate over time
- Jet cells now have diminishing force at high speeds
- Minion neurons now move toward your cursor while you hold the seek button, instead of just when you quickly press it
- Added temperature property to cells
- Some plants now have procedurally generated body plans
- Added explosion tool to sandbox mode
- Some new sound effects

bugfixes:
- Fixed setting for reflections being inverted
- Fixed framerate slowing down after minimizing the game window
- Fixed crash from imbuing mutagenic poison with a combo cell with a long name
- Steam overlay will be automatically disabled for certain graphics drivers where it was causing issues
- Fixed sticky cells not sticking to self-colliding cells on the same body
- Fixed combo cells from other creatures showing up in sandbox mode
- Fixed creatures with no cells sometimes not being deleted and existing at 0,0
- Fixed some graphics buffers getting initialized with garbage data after changing certain video settings
- Fixed disconnected parts in your body plan not getting applied immediately after being connected to by cancer cells
- Improved plant placement to prevent them from spawning out of walls as often

misc:
- Updated main menu background
- Auto-saving is now much faster and runs in a separate thread
- Significantly improved performance of physics simulation. This involved a major rework of the physics systems, which might make some things behave differently than before
- Slightly improved audio system performance
- Tooltip text now wraps
- An error sound will now play when your body plan fails to apply due to being over budget. This can be disabled in the game settings.
- Removed limits on maximum numbers for various things, including cells and particles. Memory usage will now increase as needed until your computer runs out
- Added get_combo_id function to the lua api
- The C++ code for creature behavior is now available as a reference for modders in the data/scripts/creature_funcs.h
