If anyone is thinking about taking part in the jam but isn’t sure about how to use Kwyll, the Jam specific version can be downloaded and used now, the time limited license code on the jam page is active so you can have a play before the jam starts. https://indigobeetle.itch.io/kwyll
Also, I've added a comprehensive getting started tutorial to the docs to show how to go from nothing to a basic game. https://docs.kwyll.com/user-guide/tutorials/first_game_gem_patrol.html
