I don't know about anyone else, but I found this puzzle seriously hard! Even with some deductions that massively reduced the problem space [spoiler: with regards to the number of leaves in non-numbered rows and some rules about zones in which those had to go] there was still a large amount of complexity and a fair amount of backtracking/brute-forcing.
Definitely the hardest Snakes puzzle (having now completed them) and possibly one of the hardest on the site!
(Makes me wonder if there's an additional key that I never found...)
