Wow, 54.9-54.12.1.6 with no lives and no items. 6 is the one with the blobs in the middle of the horrible area, right? That's the one I finally died at.
Of course, unless I got a big points item (I died with 2.9 million, bbut not much closer) or a nice clearing item, I was boned at metal 8 this time, but wow, those levels before that were intense!
