Hi,
Do I have to upload my game to itch.io in order to join the feedback fest? I only have submitted it to Steam. 
And do I have to submit a full game here or just a demo for the feedback fest?  

I got a couple nearly finished games I would love to finish for Feedback Fest. Am I allowed to submit more than one?

I see that judges will be reviewing submissions and rating games by overall fun, UI, art, and music. As a participating game dev, am I expected to give feedback on other games as part of  my participation, or is that optional?

Can our entries for feedback be already finished, or do they need to be finished during the submission window only?

I have a game I submitted to another jam that I really liked, but it got almost no views. I have no plans on changing the game itself beyond improving the itch.io page. Would it qualify for the jam?

How often are we allowed to update our games during the jam?
