This is a delightful and engaging game where the player tries to build up his kingdom by sending citizen characters on a variety of tasks.
As stated in the review there is no blood, but there is the notion of conflict (e.g. combat w/ monster turnips). I think the fact that the citizens have names and the player can develop feelings for them is good, and when the "die" a feeling of sadness. As king it is your job to take care of your people. I think that in game compassion and a sense of loss is much better than senseless killing w/o any concern.
As for innuendo, there is an off reference to cleavage, but when citizens fall in love, sending to get married is not a bad thing.
