For this jam, are you looking for games made during the jam or are all games accepted?
It would be better for games to be made during the jam. However, I do not set such a rule, so you can still use the games you started before. People may judge you differently because every participant will be able to rate your play.
I don't mind getting harsher feedback. This project is my biggest project ever. So I hope it turns out good if anything. Thanks for the quick answer.
