One of the things I love about game jams is that they're perfect for perfectionists and procrastinators (I may check both of those boxes). You have 1 month to complete a project. You don't really have the time to get hung up little things or drag your feet. The important part is having fun and ending up with a completed piece of work. You'll be amazed with what you can do when you have to get out of your own way and just let the process happen.
