me and my team mate both clicked  join the jam, do we both need to submit the game or will only one of us need to ? thank you :)

You should only need submit a single project, if you both have an itch account, you should be able to add your partner as a contributor for easy access. Otherwise only one person needs to submit. Than that single game, is the thing that's submitted.

Thank you ! I appreciate the help :D Best of Luck ^^ and cant wait to play your game ^^
