Hey , I just published a little game where you can place lines to change the balls trajectory and make sounds this way , you can also move the cannon and change its fire speed and rate , It's just like a little sandbox thing I made to try new things with the physics, especially with the repeller and attractor. Thank you for trying it! ?•?-•?
