You have a License file which is great, but you'll need a README as well (these are two main criteria for open source category).
Physics is cool, great concept, add some music and sound effects for more immersion.
readme has been added cant believe i forgot that duh! thank you for the feedback will be sure to work on that
README looks great, love the emojis, you can always spice up up further with screenshots, or gifs of your game.
