You begin by getting candies, which are represented by a counter ticking up. As you eat candies, parts of the game begin to unlock, beginning with a save button. You can also buy things with your candy supply in the village shop. Clicking MAP in the task bar will open it, allowing you to explore the town. Minimizing it means you can eat more candy!
