A lot or a little?
Parents need to know that Doodle Invasion is a fast-paced arcade game in which players prevent alien invaders from landing on a beach by drawing barriers to catch them so they can be sucked up through the hoses of rescue ships. Players must also defeat the alien mothership by launching missiles at it. The violence isn't graphic, owing to the fact that the game looks like a rudimentary hand-drawn cartoon. However, frequent uses of "s--t" mean parents might want to think twice about letting younger kids play this one. Doodle Invasion HD is available for the iPad for $1.99.
