This is not my video, but I'm sharing because it makes this trophy so easy. It explains in a very approachable way every strategy and commands you should be performing,
It is a 22 min video with full comentary, from a channel called SweetJohnnyCage:
You can just play along from save point to save point, and you'll get the trophy in no time, possibly with very few deaths. I was dreading this trophy because I don't enjoy old school castlevania too much, and had an unpleasant time with Rondo, but this was surpringly easy, don't believe I've died once.
