Hello I want to know some answer.

1.Can I submit demo games ?

 - I have old project but I want to join this event.

2.Can I add feature Auto Update in game when I submited?

 -  When I released some my project maybe found some bugs later,So I want to  add this feature to update my games and add new content later.

Thank you

Old projects aren't allowed. You need to create it for this contest. There is nothing in the rules that prevent auto update. I don't think it will matter a huge amount as the judges would presumably be downloading at the end of the contest. I would hope anyone who enters the contest would know to grab the last version when the contest ends to take a look. I suppose it could be a problem if you keep updating after the contest ends and before judging completes.

Old projects not allowed. The game must be made within the one month period. Auto-update would not be allowed to update from the end of the contest period to the end of judging, as changing your game after the contest deadline would disqualify your game as not all work was done on it during the contest.
