For what it's worth, my game (Terramancers) still works out of the box (plain Java, not much that can go wrong), at least as well as it did originally.
Pretty interesting to look back at a quick project I made almost ten years ago. I'm actually still quite pleased with it, I think it was a good concept prototype that could in theory become a proper game, but the audience (and competition judges) wasn't there. I love experimental multiplayer gameplay, but the community seemed to be more into story-driven RPGs.
As others have commented, it's hard to expect a game jam to produce any mature games, so the question is what follows up after the jam. I think the LPC was done very well until the competition ended, but then the long judgement time and zero followup were points to improve. If someone was to do another one, I'd recommend doing the same as LPC up to the end point, but then follow it up with some post-jam feedback and discussion of the games. I literally didn't hear anything about my game other than a couple of (third-party) bloggers who did some "checking out all LPC games" posts, so naturally I didn't think developing it further is going to go anywhere.
I'd say even if it's (initially) a bad game, getting some feedback from the organizers with some tips, some comments about each game would make it much more likely for those projects to develop further. And also trying as much as possible to increase the visibility of the games - right now there's basically no way of estimating which game might suit your taste other than trying them one by one. At least a page with some description and screenshot of each game would be a minimum. So even if the judges/organizers are not into your game, maybe someone out there in the audience will show up that happens to be super into the kind of game you made.
 Unfortunately I tested only on Windows and ended up screwing up with some file name case inconsistency, which on Linux would mean that in some cases you'll get a sprite not loading unless you rename some files.
