Simple puzzle game

I notice this game because of the attractive cartoons. The illustrations in the app. is good. Generally, it is a puzzple game. Nothing difficult or challenge. I understand that the game is made for kids. But I wonder do they think the game is a bit too easy? Okay. I cannot tell it. Anyway the game is fun. Just often I do not have an idea what I am doing the in the Menu page. Not sure the function of the buttons (with graphic) at the two corners. And not sure if there is a proper way to return to the main menu.
