I have mad a virtual pet Llama that does all of the following: dies when ( hunger, thirst, happiness and tiredness runs out) , gets happy if you press the ball, less sleepy if you press the bed, less hungry if you press the doughnut and less thirsty if you press the drink.
I have added at the start of the game you can interact with the pet by choosing its name and speak to it. Thank you for my friends who helped me.
