There's nothing hard in this game, maybe you have the patience to wait and play to become stronger. I think minors can play this one because it's so simple and user-friendly, you can also play it hands-off. In terms of graphics, I can say that it's very nice. I like the type of animated cartoon character. It reminds me of my childhood, because I like to watch cartoons, and it makes me feel younger! I hope some players have the same feeling so they can enjoy playing this game~
