You should be really proud that you managed to compete in literally one of the largest game jams in the world!
I thought your game idea was very creative, and especially impressive for a solo game.
I can definitely understand the stress these jams can bring especially with a super short period of time, and I'd love to share with you my experience a little bit that might help you too! This was my second game jam ever, the first one with me doing all of the art and programming while working with my music composer friend. This time I got 2 of my other friends to help with programming, and that drastically reduced the workload! That would be my advice to have the most fun out of these.
