Incredibly hard! I'd love to see the intended solution path for this because my solution was far from elegant... I enjoyed solving it immensely tho!
-----
This one was quite difficult, one where I was trying to make it tricky while exploring global entropy. I may jump back into the constraint and attempt to make a smoother/easier puzzle. Appreciate the solve/feedback.
