Last I checked it is generally allowed for small fixes, just dont go changing the entire game
From the looks of other entries, I think I can add new versions to the available downloads, and make a note on the download page that only v1.00 should be considered for judging. I want to be judged on what I complete before the deadline, of course, but I would like non-judges to have access to the bug fixes that have been made since (so far a simple fix, but very visible in a specific case I didn't catch in time).
