You can have a look at Lightbot Jr and Kodable for more kid oriented programming games.
I have started building a game where kids make their own mini-games. It will be more focused on drawing and customizing items and then using them to build the mini-games, but there will also be some programming aspects as well.
Would this be something that may interest you and your kids?
If you'd like, I'll gladly exchange with you about the topic. You can find my email on the app store or on my website (visible in my profile).
