You have a README which is great, but you'll need a License file as well (these are two main criteria for open source category). Also when you get the chance, fill out your README, you can start by adding some of the things from your submission page: https://alecraf2.itch.io/balance-master. Even screenshots etc are great.
Music is great, would be good to have a short menu or intro screen instead of the game immediately starting on open. Love the idea, I think the controls might be a bit too aggressive, they go too far one way. Great work on your submission and you've got a solid foundation. Would also be great to have some sort of counter; either timer or similar to keep track of how long you are balancing for. Could create high scoring system or similar.
