Hello! I'm having a quality game ready to be released on Steam, but I'm having a bit of trouble understanding this process in writing. Could you make a video or even a tutorial with images to make it easier to understand? What if I can not do this procedure I will not be able to put my Construct2 game on Steam?
Probably shouldn't use this with linux/mac just yet.
WTF is this crap. No install instructions and all it gives you is some web file. This is not a C2 Plugin.
There are instructions for installing addons in the manual: scirra.com/manual/158/third-party-addons
There are further instructions here in the 'Documentation' tab: construct.net/construct-2/addons/83/greenworks/documentation
