Why are all animals in the game silent? Are they all severely autistic and unable to communicate? Animals such as birds, boars, bears, cows, sheep, should all make noises and sounds, bears roar, cows moo, sheeps baa, pigs oink and so on.
But not in this game! Not in this game! Easy fix, just warez some sound effects and add them to animals.

Could also hire some nigerian guy like this to make you royalty free sound effects. I'm sure they'd not ask much due to geographical economical differences!
