This is an interesting approach that seems like a good complement to Robot Turtles. Whereas Robot Turtles takes a more open-ended "create your program and go" approach, Code Monkey Planet is focused on strategic use of more complex control structures. I'm personally on the fence about the recent movement to teach kids programming at a young age as evidenced by all of the financially successful Kickstarter projects and summer camps aiming to do so. Personally, I would rather see things that teach kids about programming and then let them decide whether they want to pursue it or not.
