I remember looking at this. It's such a shame that it's no longer maintained because it would be handy for some people for that do not want to dig into Electron.
Though, perhaps someone could make a new wrapper thing someday.

Yes right now, it is the simplest way to turn a page into an Electron executable.
It still requires a bit of installation; the only way I imagine to make it even simpler would be if the tool was made into a self-contained distribution that wouldn't require installation, or if it was made into a web app where one would upload a zip with the page they wish to package, and it would return an Electron-based distribution.
Yeah. I might look into it at a later time when I do have a game made.
On the topic of Pocket Platformer, I don't know if you already know this (which I think you already do), but the latest update now have not only base64 audio, but also images as well. I don't know how well Nativifier would handle a single exported HTML file of a Pocket Platformer game with base64 code, but I'm sure not much will break in terms of compatibility and stuff.
