So, hopefully this isn't entirely off-the-wall, but...
What're your thoughts on bundling what you can (easily) find of a level's context with it? Probably at least the blurbs you have on your site, but, like, stick a text file in the world folder and stuff it with reviews or development logs or whatever. For example, I know with Endless Winter there had been plans for alternate endings that got scrapped because of (if I recall correctly) exhaustion and wanting to finish. (Not to mention the worldbuilding stuff.) I know this because I'd read the round robin topic*, and it'd be nice to know that this sort of information would be available to anyone playing a level in the future, even long after it's been wiped from the Web. A time capsule, of sorts. (It's interesting to play Don't Eat the Mushroom and see a picture of a forum that no longer exists.)
(Obviously, this would all be going forward, if you wanted.)
*In collabs rather than level previews, I think. Unless there was another one in level previews.
