I haven't. I've been stuck on that level in SMG2 for probably about 2 years now and never could finish it. I still try it every now and then (I've been trying it all throughout this weekend) but can never complete it. I could really use some tips; the farthest I usually get is the area with the Pull Stars, but I got to the Hammer Bro. area today, which surprised me, but I then died in that area.
