Imagine trying to negotiate your way out of the interior of the ship when the floor is pitched 80°. Hall ways would become near vertical shafts with nothing for a foothold except perhaps door frames. Scary stuff. It’s like The Poseidon Adventure in 10 feet of water.
You are spot on.
IIRC, there was a discussion of this in the last day or so where one of the passengers who got out described almost exactly what you said.
Only no annoying theme music.
Cheers!
