No worries. No game jam game is perfect. My first attempt at making a full game also became too full of bugs for me to manage. I learned a lot from the attempt tho and decided to take that new knowledge and try to make something simpler. That simpler project is going really well, and I've learned a ton from that project as well. When it is done I think I will be able to revisit the idea I had in my first attempt. So don't give up! Buggy broken games are a necessary step to making a complete successful ones :)
