Parents have almost nothing to worry about. As a puzzle game, Zooo features even less violence than most E-rated games do. There's no nudity or sexual content. However, there is a panda that sometimes says, "Whew! Damn it!" when one's game is over.
Puzzle game fans won't find this game groundbreaking, but it is addictive and fun. It's easy to learn and a challenge to master, as all good puzzle games should be.
Deaf and Hard of Hearing gamers should have no problems playing Zooo. All instructions are in text and there are no significant auditory cues.
