Indeed, it's a weird quirk that itch allows updates after the game jam is over. I'm going to take your word for it that it was just to make the build smaller. Next time we'll definitely be looking at other jam options (or roll our own) - this is a good learning experience for us as jam hosts, and we really appreciate the feedback! Thankfully, we did play them all as they were submitted, so the final judges decisions - outside of the community votes - won't really be affected by late updates.
