Hey Elijah, I know what it feels like! I've participated in so many of the Speedgames and so many times I didn't even submit on time! So my game just was left super unfinished, and not fleshed out enough. And the ones I did submit, only a small percentage could even be called a complete jam game.
But your thinking about learning skills and new things, and using those skills for the Lord is right on point. Always something important to remember! The rest is just craftwork, trying one's hardest, and keeping at it!
