I've asked all projects with a "N" on that list to provide source code if they want to be eligible for winning the jam.
I know that CowThing can't provide the source code for Frog Smith as they did a blunder when trying to upload it to GitHub and deleted it locally before it was pushed online (allegedly, but CowThing did provide source code for their previous jam entries - winning two Godot jams - so I tend to trust them). Rules are rules though so we'll have to exclude Frog Smith from the final ratings.
