In Black Sheep Acres, you must defend your wall from an onslaught of forest animals. You will earn money for each animal you kill. After each level you will have the chance to purchase new weapons, ammunition, wall repairs and specialty items. When animals reach your wall they will start attacking and depleting your health. If your health reaches zero, the game is over. You can buy new layers for your wall in the item shop which will increase your max health. Now go kill some animals!
