All newsPlayers around this dateRead on Steam

Resurrected the scenarios

  • Tested and rebalanced all scenarios to work with the new features of the movement update
  • Redesigned the soil statistic button to have a planet icon
  • Added new terrain overlay steepness stats and climate zones to all scenarios
  • For all scenarios, added new limbs to 'anchored body parts' (which don't require mutations to reach) wherever it made sense
  • Prevented plants spreading all of their seeds in the beginning of their life (which could happen with large seed surpluses that the disaster scenario requires)

Resurrected the daily challenge

  • Linked the new random terrain generator to the challenge generator
  • Made the 'ocean floor walker' leg always unlocked, to give players easy access to the new arthropod limbs if they want to
  • Disabled terrain editing tools
  • Fixed the upper half of the 'let's go' button not registering clicks

Fixes for small map sizes

  • Drawing stats no longer causes the game to freeze (thanks, Jupiter hater!)
  • Switching to smaller map sizes while in manual stats mode no longer causes the game to freeze (thanks, Jupiter hater!)
  • Meteorites craters now appear on the correct location (thanks, Jupiter hater, azul1462, Col. caboose!)
  • Hovering continents is now (much) more precize
  • Volcano smoke now appears above the volcanoes
  • Highlighting continents now continues to work after editing the terrain

Polishing the walking animation

  • Revised walking animation parameters for the 'hoof', 'webbed', 'sturdy walker', 'very sturdy' limb, 'hangs upside down', 'lightweight webbed foot' and 'sharp talons' limbs
  • Remodeled 'fast two-toed runner' to better work with the walking animation

Fixes for upright animals

  • You can no longer by accident attach the sessile foot to a slot that is not the bottom one
  • Fixed how animation bones are connected for upright animals

Misc

  • Fixed the limb stats in the animal editor showing the max weight for walking where it should show max weight for climbing (thanks UltraNeonGodPet!)
  • Made fade animation more robust to edge cases
  • Made it possible to select continents very far away from the camera mid simulation
