to make a build of your game go to top left corner, click the button there, go to build settings, click build, and select an empty folder, you will have a build of your game, then, zip the folder and send it to itch.io as you can't send unziped files
Oh I didn’t know lol. This is my first time entering a game jam and overall really making a complete game. Am I able to change the game during the jam.
