The dimetrodon has a new model, new animations, and 5 new skins.
Movement acceleration works a little differently for the player now.
Turning rates for creatures are now dependent on their size category (Tiny, Small, Average, Medium, Large, or Huge) and body type category (Bulky or Lean).
Turning rates are now also dependent on the creature's current acceleration rate.
The player's footstep sounds can now always be heard by the player and are no longer 3d sounds. The sound files are quieter for the smaller sized creatures.
Footstep sound volume is no longer determined by the size category of the creature, or the growth stage of the creature. I'm already choosing different footstep sounds for the different size category and growth stages of creatures. Now the volume is just set to the maximum and the Unity Engine can handle the volume level based on distance to the camera.
