No worries, everyone's first Jam is rough, but you've learned from it, and improved for the next time. You've learned about budgeting your time, and where you can put your resources, as well as scope. My first game jam was on Ludum Dare, so its not in my itch history, but it was a train wreck. It didn't work at first, one of the levels was incompletable, the game was obnoxiously hard, and there was no Sound at all. It wasn't a good game, we got overzealous with our attempt X)
