Hi, thank you for playing, that first throw is meant to try and teach you the arch of the throw, if you stand on the lowest part of the floor and space yourself correctly it will be thrown to the top floor and slide into the button, alternatively, you can also stand on the edge of the top floor parallel with the button and throw and the orb should bounce off the platform above you and into the button. There are also some wonky ways in which your players movement can change the arch and speed of the orb and it can sometimes result in a throw at the ground and a slide with no air time. Hope this helps!
