Currently, I'm testing something I got a hold of, some other user managed to make a semi-working extension for game maker to use the new newgrounds.io instead of my old extension that works with the old API and is being discontinued.

Right now, this extension allows the game to use only medals and scores. I'll be putting some effort to make it understandable how it works (like the old one), but also, I'll try to expand it if I can.
