I don't remember using it much before it shut down. I appreciate that it existed, as much good content existed, there was a lot more awful of everything. Maybe it improved as time went on.
My memories are mostly of Super Mario Crossover. Great game, you can find it on flashpoint.
I started using adobe animate around 2022, but decided to use flash pro cs6 for now. I wish i had more motivation for animations, and i know nothing of actionscript.
There's also HaxeFlixel, which rfom what i've read, is mostly built upon actionscript 3.0. Fnf is made on it
Don't like rating stuff but i'd say... 84/100
It's a very important thing for the internet
