So I've played this game before, sank about 200 hours in to it and I'm going to run a Death March 'speed run'. Quotations because of the length I think this will take and because it's my first run.

So how long do you think this will take to complete glitchless, is it possible in one sitting? Any help would be appreciated.

My name's Baron, New to running.

What would count as a glitchless run? Would skipping the gouls in the beginning and going straight to town be classed as a glitch, or would that just be skipping a fight? Also, if anyone could provide any help on things to watch out for during this run, it would be appreciated.
