Can we continue working on the game and push changes to our repo on Github after the deadline.
(We won't change the build on the project side)
I mean I am not part of the organization team, but I think if you just tag the most recent commit you had before the deadline finished and call it something like "GameOff Submission" or sth like that, there would not be any issues, since you can obviously see the commit history. But that's just my guess :)
