I've been working on it for over two years; its first iteration was as a workshop for beginning programmers with just basic Python knowledge. I wanted something that would take abstract code and make it visual, interactive and fun. Now, after many iterations, I'm launching it as a small web game.
To try the beta:
1. Create an account (to try a demo without signup, go here[0]).
2. "Start tutorial"
3. "Buy" (top right) -> "Join Open Beta"
I'd love to hear your feedback!
Behind the scenes, Brython[1] is used to run the code. I'd have preferred pyodide or micropython (and might get back to doing it), but both ended up having technical issues and Brython was easier to integrate.
Cheers, and hope you enjoy!
