I'm a male Klyros and am having the SAME tilting problems. I fell off the edge of the world and died and had one heckuva time trying to get out of the DR because of tilting and running on my back or on my face, trying to climb stairs, etc. I found hitting the 'z' key would get me back to upright position for a short while, but trying to climb that last set of stairs out of the DR was extremely hard. I did make it out ok and try not to die now.
