A lot or a little?
Parents need to know that Edge is a physics-based puzzle platformer game involving a simple mechanic: Move your cube from the beginning to the end of the level by rolling it in different directions and adapting to challenges like conveyor belts, uneven terrain, and moving platforms. There's no objectionable content to watch out for, but the game does require the kind of fine motor control and critical thinking skills of a child of perhaps 8 to 10 or older.
