Flash Player is officially discontinued and not supported in web browsers anymore. Windows has also surprised us via an update preventing Flash Player from being run on Windows anymore, rendering the Newgrounds Player temporarily broken.
I make this post even though Fulp already made a post on the site about all this, because I know people are gonna message me or comment on my games that run in NG Player bein' like:
"NG Player stopped working on your game what the crap?!"
If you'd like to temporarily get NG Player working again with a little wizardry, follow the Better Solution in this post (don't uninstall Windows updates unless you're a daredevil).
NG Player is also going to be updated to bypass this issue, and eventually far into the future Ruffle will support ActionScript 3 and we won't have a need for NG Player.
Keep on Flashin', kids.
