No matter what engine, framework or library you use, it is important that you start the setup before the jam starts. so make sure you have a barebone project ready if you haven't already. it's also helpful to setup other things like a github repository and make sure all your usual software are working and dont need any updating or troubleshooting.. for me for example I use the godot engine, so I have a (jam-template) project always ready. it has common components like -A global scene manager with premade transition effects -A global music player that can play sound effects and handles music and music transition. -basic customizable splash and menu scene -common sound effects like buttons and splash scene music and some other utility and misc I use
