Multiple ways to get 233. In fact it seems to me that most of the reasonable paths I try give 233; I think around a half-dozen ways. It feels like there should be a 231 but I found none so far.
OMG, for me, this was DOUBLE shocking. First, I couldn't come closer then 8 off, then I was one time going too fast and moved something I never meant to move but went on and later discovered it was USEFUL! Very unusual, really shocking! Auuuuu! :) GREAT level!
