Any ideas or platforms for game development for a nine years old kid without any real programming background? My kid is finishing Blocky Games from Google. I think it was a good start, he isn't hooked into programming but at least he had some fun and learned some concepts, like loops. Now I have no idea on where should I guide him to now. I was thinking about Python Turtle, but he will probably get bored. Will take a look at Game Maker, but looks too much for a kid, good for teenagers perhaps.
