I'm guessing this plugin is retired? It's listed for download on the website, but the author turned off comments on it and disabled its bug tracker and everything but I can't see that it's explicitly stated anywhere as abandoned unless you spend a lot of time looking into it.
I bring this up because I was using the plugin until a C3 update made my game no longer able to start if using the plugin. NWjs would open, but my game would never even get to the loading splash or anything. I think the plugin should be removed from the website if this is the case. There's no way to get support for it, so you can't find a way to address this even if it still works.
I wanted to change my vote to a thumbs down when it stopped working, but apparently this website won't let you change your votes.
