A lot or a little?
Parents need to know that Krystopia: A Puzzle Journey is a puzzle game for iOS and Android devices. It has no objectionable content, and you simply solve a series of brain-teasing situational puzzles. But they can be difficult, and the game doesn't explain its mechanics at all. Also, while people can play the beginning of the game for free, it costs $2.99 to play the entire adventure.
