Very nice, I enjoyed finding the many points at which the structure began to give. Very nice manipulations, I can't optimize it at the moment Such a great one, again!
Enjoyed it! Just like Yokosooo, I first had a 197, too.
Very nice one! had 197 before solve, cool one was at 129 for a while, as I was placing the block inefficiently
very neat and nice for its size as described :) This wasn't easy to see. I was stuck at 184, for quite a while.
