Player movement part 2

Some feedback I received on the movement was that the green character wouldn't go back to following the player, I've added it so that clicking on any characters will cause it to follow it.  I've also fixed the characters rendering priority which got pointed out as before the green character would always be in front of the blue character.  I've also tried adding a jumping animation for aesthetics and a shadow to show it off, I also added another green character to showcase the following other character feature.
