I have created a project for another jam with the theme of ink. I was only able to work on it for 4 hours, and I was frustrated that I didn't have the time to put as much effort into it as I wanted, resulting in an unfinished project. So I'm wondering if this jam allows previously made projects?

Hello!

From experience in previous jams, as long as your game fits the theme, yes, you can! But I'm not a moderator, so can't say for sure
