After playing a  while and getting a go feel of it the user interface is god  graphically but need to allow   thing like  mouse clicks and dragging the abilities around to order them the way the player wants.

Another  thing is  pressing the mouse on the grenade or #4 ability in the UI  should give the ability use  circle to  either  throw  jump or  drop a turret.

Also reloading should be  clickable on the UI too.

Just my 3 cents  and  hope   these  will make it into the finished game.
