This is another physics simulator, but it has vertical gravity and other functions. P.S. The interactive platform is kind of glitchy but its the best I could do --------------------------------Controls------------------------------ [D] - toggle drag effects (slowing down) [C] - change costume [V] - change background [G] - toggle gravity [S] - slow down [P] - show interactive object [N] - move interactive object [Right arrow] - increase horizontal velocity [Left arrow] - increase vertical velocity Click, drag, and let go along background to slingshot the ball
