I am a mobile game developer but unfortunately I cannot use C2 for my professional work due to the lack of plugins that me and my publisher require. I need to integrate Heyzap in my projects but unfortunately I don't have the technical knowledge to do it on my own.
There are official made Heyzap Cordova plugins made by Heyzap and you can find them here: https://github.com/Heyzap/heyzap-cordova.
I would require a plugin for Construct 2 to call banner, interstitial and video ads.
If interested please PM or email for more details.
