Patch v12.37

Fungus changes


  • Removed expected age: now, as long as there is detritus in a location, a fungus has a 90% chance of staying alive. This means they can become very old.
  • Fungi now live in cycles of 60 days, only showing themselves the last 20 days of the cycle. This prevents every world being full of mushrooms all the time.
  • Made larger fungi less likely by decreasing temperature and wind resistance with size
  • Fixed inverted temperature resistance statistics when hovering a cap in the editor
  • Added a LOD mechanism to mushrooms, so they dissappear when you zoom out, to save performance


Grass changes


  • Made short grass better in low temperatures and long grass better in high temperatures, and vice versa
  • Tiles with grass now always have detritus, as it represents a constant cycle of grass plants dying (and being replaced)
  • Fixed plant behavior when dropping grass in a place that already had a plant: it no longer becomes transparent, and no longer moves a bit as if replaced


Improving random mutations


  • Added leaf scaling to the random mutations system
  • Fixed potential illegal state that could be achieved by mutating some fin types in subslots
  • Fixed mutating carapaces (turtle shells)
  • Fixed plants with detached roots
  • Found and fixed another reason that caused animals to incorrectly show plants as their ancestor


Balancing leaf stats


  • Added more variation and intuitive statistics to minimum and maximum temperature
  • Buffed moisture resistance, to open up a larger part of the leaf tree to wet planets


UI fixes


  • Shortened top row button tooltip delay
  • Fixed 'millenNia' typo that has been there for 5+ years :(
  • Better error message when trying to create an animal that fertilizes eggs externally, but doesn't lay eggs asexually


Plant view fixes


  • Fixed position of large leaves when moving in the wind
  • Fixed plants far away from the camera continuing to move fast when the player switches to normal time speed

Patch v12.34

Fixing bugs that show up in long running simulations


  • Fixed a gamebreaking problem that could emerge with hormone instincts after an animal lost a hormone
  • Fixed a save file corrupting problem related to saving instincts and diets for the non-default sex
  • Removed various log messages slowing down the simulation when sped up


Balancing plant evolution from algae


  • Areas automatically get their nutrients filled up by nearby water, so in these areas plants can evolve without the need for fungi
  • Added more random variation to the 'starter plant' that evolves from algae
  • Fixed a problem where the shown statistics of the stilt (mangrove) roots didn't match its statistics in the simulation, leading to plants not growing in 'high moisture, max softness' areas


Fixes for the daily challenge


  • The daily challenge now uses a less extreme variant of the planet generator, to prevent planets that are too hot or windy for starter organisms
  • Medium moisture is now the default planet setting (instead of maximum)
  • Fixed seed selection mechanic, so it should no longer be possible to get the exact same daily challenge two days in a row
  • Fixed bugs that caused the daily challenge to not always lock for the day after trying
  • Fixed 'animals that change sex during lifetime' objective not registering
  • Time is now paused until you click 'let's go'


Various changes to the animal editor


  • Sleep pattern buttons are now greyed out for the smallest body size, because their lifespans are so short that they will die before they get tired
  • Dropped support for multiplacement mode (CTRL)


Performance optimization


  • Hearts to indicate mating now only appear when the animal is somewhat close to the camera
  • Zzz to indicate sleeping now only appear when the animal is close to the camera
  • Merged all colored spheres for the flypaper trap into 1 object, so they no longer have a measurable impact on performance (fewer draw calls)


Other changes


  • Fixed a bug where opening the detail view for multiple species in quick succession caused their names to be mixed up

Patch v12.32

Changed all scenarios to work with the new mechanics in the Scary & Sexy update


  • Decreased moisture in 'beach', 'disaster' and 'flower' scenarios, to better reflect what primitive leaves can handle
  • Changed the milestones of the 'first animal' scenario, as sight is now required to eat
  • Fixed instincts based on sights actually activating
  • Made temperature rise in 'greenhouse' scenario less extreme, because evolving heat losing body parts has become harder
  • Changed the helper notification in the 'greenhouse' scenario to focus on skin and eggs (instead of body parts) to beat the heat
  • Fixed plants with various seed types not triggering the final 'flower' scenario objective
  • Finally removed 'ice age' scenario
  • Added icon for 'swamp' scenario


Further tweaks to the scenarios


  • Made the sea in the 'first animal' scenario deeper, so you can use the just introduced plankton in a larger area
  • Hovering an organism over terrain where nothing is allowed (for example, because it outside the play area) will no longer show terrain stats
  • You can no longer place organisms outside the play area
  • Made scenario clouds less bright, so the bloom effect (to highlight bioluminescence) in the evening is less extreme
  • The clouds in the greenhouse scenario are now a little higher, so they don't block the view of the plants
  • Made pollination occur also if the nectar eaters choose to eat other food (making the 'flower' level way easier)
  • Made 'completionist' achievement more dynamic, so it does not matter how many scenarios I add or delete


Tweaking mouth part stats


  • Revised the mouth part evolution tree so you can see some air breathing mouths without using the arrow buttons
  • The 'attractive mandibles' now evolve from the 'larger mandibles'
  • Made the 'nectar feeder' and 'nectar feeder with external parts' much better at extracting energy from nectar
  • Decreased the hitbox size for the 'semi aquatic plant eater'


Other fixes


  • Various fixes to remove incorrect family tree lines in the plant and animal editors
  • Eggs that are not the default land/water hybrid eggs now also have hover labels telling you what species is inside (instead of FPS eating errors in the log file)
  • Fixed the archive button
  • Made sure the leave buttons (to main menu or desktop) continue to work, even if the autosave right before it fails

Patch v12.31

Save file format 10


Loading save file version 9 is still supported, but if you click 'save' now the game will also remember:

  • The secondary color of juvenile stages and other sexes
  • Traits specific to juvenile stages and other sexes
  • Instinct and diet options specific to juvenile stage and other sexes
  • The birth locations of species
  • In the species detail view, not only which species your species is eating, but also in the form of what food type (eggs? fresh meat? etc)
  • Fungus organism caps
  • Fungus mutation chance
  • Energy collected by living plants and animals (to increase the chance they live through the night)


Fixes and changes related to saving and loading


  • Fixed a problem where plants died after saving and loading: the game incorrectly thought all plants were in an environment too wet and without nutrients
  • Added an autosave when exiting the game
  • Removed needless logging from the save/load process, making it much faster
  • In the savegame list view, sandbox saves now show the sandbox icon
  • You can now save scenarios before completing the first objective without the game crashing
  • When loading a scenario, night cycle periods are now set correclty
  • When loading a scenario, allowed alga and plant colors are now set correctly
  • Fixed a crash when exterminating populous species immediately after loading a save
  • Added save file versioning explanation to the load view


Working on the daily challenge


  • There is now a main objective view before you start, including an explanation you get only 1 attempt
  • Starting the daily challenge now only 'counts' AFTER you click 'let's go' in this new objective view
  • Added events like meteorites to the objective description
  • Fixed time stopping bug when the meteorite hits the world
  • Removed options to the retry from an autosave (which didn't exist anyway) if you fail


Tweaking the manual mutation mechanics and UI


  • Removed the option to mutate organisms that didn't reproduce yet (but just survived long enough) because this messed with the species counts... I think it contributed to the negative population size problem
  • Removed 'mutate' from the dropdown menus in the sandbox, as mutating doesn't make sense in this game mode
  • Removed the 'mutate' button from the organism detail views
  • Added a mutate icon to the species detail view, but only when mutating is possible (so not in the sandbox)


Fixes for the juvenile stage in the animal editor


  • Fixed bodypart hitbox sizes for juveniles
  • Fixed a crash that sometimes happened when resizing body parts of a juvenile animal


Mouth statistics balancing


  • Added grass and fresh meat energy for 'semi aquatic plant eater'

  • Added marine snow to 'marine snow feeder'


Fixes for body part positions


  • Further polishing of body part positions in subslots

Worked on random mutation behavior


  • Revised the random mutations system for instincts, so it can handle all new instinct extensions
  • Added new diet options to random mutation system
  • Added hormone mutation
  • Incorporated all new skin patterns
  • Fixed various statistics that were not correctly changed when a bodypart is upgraded or downgraded


Fixes for the grass visualization
