This one was annoying to do because I had to remove the shotgun which is usually required for the level and edit a bunch of rooms. The third-to-last room is so hard and tight, of which I had to also change to make possible. Maybe it's possible normally but it's really hard and I personally couldn't get it. Wasn't a huge fan of the regular level too.
