Thanks for sharing! This is really cool. I maintain my own learn-to-program site, so I have a sense of how much work this is.
One interactive component that we use heavily that might interest you for futurecoder is what we call an interactive walkthrough: https://www.learncs.online/best#interactive-walkthroughs. It's like a video but preserving the interactive nature of a playground. Students really like them, and enjoy the opportunity to hear multiple explanations for the same concept when they're stuck. (We're working on popping this out for external use, and have a library in the works that you may be able to integrate with a bit of work.)
I have no idea what your educational background is, but if you ever want a stable position that supports your educational innovation, consider applying for a teaching faculty job: https://go.cs.illinois.edu/teaching-faculty-hiring. (Currently our openings require a Masters degree.) We need more creators in computer science education.
