I'm unsure of the potential popularity of it, but Doom, Duke Nukem 3D, Ion Fury, and Wolfenstein 3D all have 100% secrets categories. Could we potentially add this as a category? Obviously, this is entirely up to you guys. It's a category I personally have been interested in though, and would be happy if it was added.

yup, added it!

Follow up question, since a sixth secret was added should we move the old 100% category off to category extensions or remove it and make a new one, or would that be totally redundant? The sixth secret adds a significant amount of time unfortunately.

Hmm, I think I'll just remove the other run, since there's only one and you did it, if that's ok with you of course, and then it can feature all of them I guess bwl

That is a-okay with me! They're from an old version of the game anyway.
