This worked really well, the controls are simple and intuitive, and the cows reacted responsively to my movement without feeling too easy to herd so it feels pretty therapeutic instead of frustrating. Really like the subtle animation when running or idle on the character. A bit of variation in the Moo-ing length and sound levels would definitely go a long way, and it would help if there was a wider border just to let the player not panic that a cow isn't ever going to run too far away. Well done :)
