Its been a while...but it seems thai i have a similar problem with this level.
I can't open the double door to the Throne Room.
I killed every enemy on a level, explored everything, but there is no switch mechanism that i can found.
I watched walkthroughs on YouTube, but these doors are just open in them.
I've also tried pushing myself through this door with stackable items, but I get stuck halfway through.
This is the only topic in a whole Internet with this problem
So maybe someone has come across something similar? Or some options that i can skip the rest of the level or get behind this closed doors?
Thank you in advance!
Same problem occures to me :/ Maybe we are not supposed to clear all the guards? I don't know what to do now, I can't find any mechanism or stuff...
