im working on this game that requires voice control in order to play it and i ran into this issue where the game just doesn't pick up my mic at all, and i am sure that it isnt a problem with the game so does newgrounds just not support voice control or something? and if it doesnt is there anything i can do about it?

If you run the your game locally (from your hard drive and not uploaded to NewGrounds, and running from the index.html file using a browser and not in a game engine's editor) will the microphone work? If it works locally but not after uploading, then yeah it's probably an issue with NewGrounds not granting access to request microphone permissions, and it would be a matter of discussing with a staff member whether the benefits of letting game devs have their games access microphones would outweigh the risks of letting random people upload whatever they want that can listen in on your microphone.

i did a test, using construct 3, and locally there is a popup that asks for permission first, and it works, but when i upload it on here i don't get the permission popup and it doesn't work
