The Flash "editor" software was a work of a genius. The combination of vector graphics editor, symbol library, layers, animation tools and code was super powerful yet super approachable at the same time. I have learned AS2 just by toying with the examples. Over time I learned AS3, then HTML and TypeScript, in this order.
One more shout out to the vector graphics editor - the way you did boolean operations with shapes based on their color has not been bested since by any other editor.
