More like, be willing to have it tested and see it broken. So that you can polish.

Yes, it's like submitting a homework just to get it done but you got solutions wrong. LOL. Anyway, I'm not a dev myself but maybe you might want to try to keep some prototypes that has been working on for some time and then you can use that for game submission. As long as it's patched enough to work, you can polish it some more after the jam.
