"Failure is always an option" whether we like it or not.
Game jam deadlines can be fudged by getting to a game. Nobody else sees what you wanted it to be. It is what it is. And if what it is, early and often, is a title screen, some gameplay, and a credits screen, that's a complete project. It's better than perfect. It's done.
... to that end, I'm hoping the judges grab ROMs now, instead of going with the first *_jam.gb file that was available. My just-in-case build from Tuesday did not have sound.
