Welcome to Candyland!

This is a pygame zero game. The original game consists of keep the garden happy by watering the flowers and escaping from the fangflower. but my new modified version consists of stealing 3 candies of the four that appear in handfuls in the landscape so that only one remains. If the police dog shows up, he locks you in a candy bubble
