One day a biology teacher told me about the movement of oxygen in the body. And then the idea came to me to make this game. The essence of the game is that the circle is moving in its path. At the lowest point, it changes color. To play this game, you need the color of the rectangle through which it passes to match the color of the circle. Use the upper arrow. Have fun! Art and code by me. ❤️ and ⭐ if you like my game! Tags #game #games #all #fun #funny #circle #circles #round #ball #endless #cycle #cycles #scratch
