Not sure how to continue from here
I think things are going well, but there's plenty more I want to do for the game and I'm afraid I'll be overscoping and end up running out of time if I try to do this stuff. 20 hours left.
In any case, even if I finish with a half baked product, I'll still publish it and the source code. This is the closest thing to a game I've made yet, so it seems game jams can help me with my prototype addiction.
