Just wondering how you want to handle the submission of projects. I think that when a project is submitted, it can still be updated without having to change the submission. I have a currently working game, but it's a good way from being "complete" (in fact, I suspect this type of game probably never really becomes entirely complete, at least if there's people easily able to update them). Cookie Clicker I understand is still getting updates (though I understand it got refactored to a new version, and the old version is largely getting bug fixes). Trimps is another game that I think is getting updates, though it's fully launched...
I'm not certain that the submitted game gets updated or not. I'm thinking of setting up to publish my game shortly.
