This was a real hit of nostalgia for me. I also started my web development career by building flash games and movies, and still haven't found any technology that comes close to being as 'easy' to work with.

I've got so many half-finished movies and games I'd love to dust off and finish, but I guess they're all condemned to memories these days.

Don't let them fade away! As mentioned in the article... check out ruffle: https://github.com/ruffle-rs/ruffle

I was able to drop that on the page of a flash movie that I have hosted for nearly 20 years and it's working again without the flash player. It was insanely easy and works great!
