Howdy ho !
Today i want to share another extension i made, this time, supporting UnityAds.
Why UnityAds? why is one of the few that accept incentivized ads (where you reward the user after seeing the ad).
You can get it from haxelib, and the instructions of how to use it, is here: https://github.com/ipsilondev/openfl-unityads
I hope it helps
