thanks but I had to do it randomly because it's bugged and all the statues look to the same side.
Sorry :(
The problem is that if you leave the room the statues reset their position, but not the movement counter, so the solution changes every time you leave and enter the room.
If you take a previous save and do the right puzzle without exiting it works, otherwise you have to go by trial and error.
It's something I just couldn't solve....
Maybe I'll try removing it directly.
