You say that it is for your players (may be you should say the players of your game, not "your" players), but you are influencing the public's votes too.
A lot of games could be updated (mine first), but we won't upload our updated games before the end of the compo.
For me it sounds like cheating, by influencing the votes.
You had the same time to post your game as the others.
So the public have to vote with this version, not your new version.
If you were not able to propose a bugfree version, do with it and wait the end of the compo.
