Feeling dumb for missing this one for so long. Found almost every 2 off immediately, but somehow was blind to the main path. Took me a long time to see, I was focused on the wrong exit... 23 attempts. Not sure if I liked or hated this level. So many clean 2 offs...however, that oddly placed block finally tipped me off. Extremely counterintuitive for me. Many 48s still make more sense to me. 5 stars for the educational value. I did go to the Wikipedia page to learn more. Carpe diem! Great one, had some work. Enjoyed it. :)
