This one is a lot of fun! I know the creator and he is a pretty rad dude. My nieces and nephews have the print version and they really enjoyed it:
As an aside I would say mine is PG-ish, similar to Harry Potter/Naruto/Sailor Moon. There is some mild innuendo, mild curse words (p-d off, damn), and mild adventure peril or violence. No sex or gore, etc. Romance is Disney-ish in content.
