BL / PY : Write a cyber pet game. When the game starts, your pet is happy but gets more sad the longer you leave him alone. If you tickle him (button_a) or feed him (button_b), you restore him to his highest level of happiness. If you leave him untickled or unfed for more than 30 seconds, he will die. Make sure you animate the pet on the screen - you can use different faces to make your pet more lifelike. WARNING : This is hard!
