Gentle reminder that there are already some great game creation tools out there including Hopscotch (https://www.gethopscotch.com), Toca Blocks (https://tocaboca.com/app/toca-blocks/), and our own Infinite Arcade (https://tinybop.com/apps/the-infinite-arcade). And of course there are many kid-centric languages like Scratch that cater to game creation.
