What i dont really like with this puzzle is how you need to keep reload the game if you plan to do it without jumping around with skills like teleport.
I dont mind puzzles, but this one is about resource management with the shambling skulls you find, and if you use one on a door to many so is the only fix to reload before you unlocked the door.
I much prefer puzzles where if you do something wrong you are just teleported back to entrence, die, get into combat etc.
