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.
