I'm in the same boat but it's like my 5th full game jam after a lot of unfinished prototypes. Keep at it! Have a look at my little games, I generally put the code as open source :)

I checked out your games - they’re really well polished. I especially liked the airplane one; it feels very complete and refined. It’s also great that you share the source code. I personally build everything using vibe coding, so I haven’t written a single line of code myself — but your work is really inspiring.
