I haven't solved this one, yet, either, but I agree with yokosooo, all in all! Looks splendid! And is a good puzzle, too (my first try ended with a terrible blunder, that couldn't bring me to even touch the exit :) ). AFter a few tries I came to 245. Will keep trying. :) Very interesting, IMO.
EDIT - wow, got it now, at meow's 227. Great find, meow. Very nice path. Not sure if optimal, though, we'll see.
EDIT2 (two years later, 10 April, 2025):
I was stuck at 213, for quite a while. Today I found 211, and then finally manti's 209. Very nice one! Also demoted from SGM to GM.
Noooooo. I barely demoted this lol.
Such a cool level. It's cool for the magic that the series has as a whole, but also it ends up having some fairly weird pipelining and a whole bunch of other interesting stuff.
