Just to give more context to this
There is a lever near the entrance of the room that turns the orbs into arrows of four colours, each colour point in a different direction, you can only move them when they are in orb form, in arrow form they will not budge an inch, so move them in orb form, then pull the lever when you think the placement is right to turn it into an arrow, then change the direction or each arrow, you can pull the lever again to change the arrows back into orbs so you can move them
There is also a box on a raised platform in the top right of the room, push that box through an opening in the platforms barrier and itll drop and break open, giving you another orb/ arrow which you will need
The aim is to line the arrows up so that when you press the button at the bottom of the room and the statue in the centre shoots.......whatever it shoots, the projectile will bounce off the arrow and head in the direction its pointing
Ultimately you want the projectile to be shot from the centre statue and then bounce from arrow to arrow until it hits the statue at the rooms entrance
Dont worry, your not alone, this one did my skull im too for about an hour
