During the follow the monk glitch (Scriptorium), we can access the tower part. From there there is another glicth with Berwal cutscene that change William hit box to have a negative height. We can then go through anything and go straight to the Abbey, the last part of the game.

Bad news is the cutscene doesn't load, so we cannot progress since the executioner is not loaded. We still have the ghost ability to go through walls, so we can go directly to the secret entrance and splash Juliette

But then we get block by the door that bring us upstair where we need to push the cross. For now I'm think there are 3 ways to pass that door:

• Glitch to unload the door by dropping and picking up items (Alone in the dark glitch), that might have been fixed for time gate
• There might be a way to trigger the cutscene, kill the executioner and then open the door normally
• Maybe there is way to get a glitched william with some saving manip, or maybe we can get into a ghost state again

here is a cheat run for this shortcut, I've used the room viewer to pass the door
