Well, just because the graphics may appeal to children as well doesn't mean the rest of us can't enjoy them. There's no blood or guts in the game, sure. The anthropomorphic animals are all weirdly porportioned, and cute. There are bright colors, and your character is always smiling.
But how is this a detriment to the game? You may not like the style, but some of us do, and some of us love the game.
