I love that you have a README and License file (main criteria for open source category). Remember to fill out your README, and you can add info from your submission page: https://redadoo.itch.io/balance-block.
Some sound effects and music would be perfect. Maybe a little intro or tutorial screen as well. Eyes on the bricks are very cute. Nice solid foundation to keep building your game. Well done on your submission and looking forward to seeing the final product.
