In this game, you will see three pictograms representing farm animals: a cow, a sheep, and chickens. You can click on the pictograms to choose which animal you want to add or subtract. After clicking, you will be prompted to enter an action, either to add or subtract a certain number of animals (e.g., "+ 5" to add 5 cows or "- 2" to subtract 2 sheep). The animal count will be updated accordingly on your farm.
Please note that this is a very basic example of a game and can be expanded or customized further based on your specific requirements.
