No goal in this game, this is just a sandbox. If you hold LMB a black arrow will appear the power of the ball will depend on the distance from mouse while launching and the direction on mouse position while launching. Press E to show or hide the variables. Press Space to reset the position of the ball. The dot shows the status of the ball: blue - idle, green - flying and red - falling.
a RATHER GLITCHY sandbox This is probably the best i could do with the ball.
