It's ok your health is more important. I am also curious on the new body parts not sure if it's supposed to be a secret or i can read about them somewhere else.
I would also like to suggest motion detection, maybe a setting for the eyes or a completely new body part. Maybe the signal strength depends on the distance and velocity of the other object? i am excited to create a predator-prey ecosystem where the prey is not dumb and can differentiate between a predator and the ground.
Don't know if this is the right place to suggest features.
