This happened to me in PP Jam #7, and I was really proud of that one, I feel you. While there’s really nothing that can be done about this, at least you’ve gained more experience in game development. There will be many more game jams where you’ll get another chance. You might even make something better than you imagined. This is the first time I’ve actually submitted something to a jam, after participating in 2 other ones and failing to submit something.
