How do we submit non-coded/textual entries?  I've got what I think is a new NP_Complete problem that's described as a game, but I'm probably not going to have time to code it up.

You can create an itch project as normal, but submit a .pdf file instead of computer code or a .exe.

I believe that google doc can export documents as .pdf files.

I guess it doesn't have to be a .pdf file, but that's what I've seen in tabletop rpgs on itch.io.  Edit: I realize that this isn't about tabletop rpgs, but I think the same file format is fine.

I updated the rules section of the jam page to mention .pdf files, but I made it more a recommendation than a rule.  It's a non-ranked jam with 6 participants so far.  I don't want to make unreasonable formatting demands.

.pdf isn't a problem.
