Why does this GitHub project exist? Recent changes to the Internet screening in the Library where I run my Code Club has resulted in blocking my Code Club Adventures website that contains this content. Annoyingly it has also blocked some functionality in the Replit IDE used for the PyGame activities. Thankfully, the GitHub documentation pages are not blocked so I'm using this as a stop gap until I can get a proper fix.
