I have one idea how this could be done, but I can't make it happen. Amazing level! Will keep trying to at least touch the exit.
EDIT (a month later): My idea was right and I finally found a way how to make it happen. 8 off, atm. Will try to bring it to 192, too.
Marvelous level!
Sorry for demoting it, I was being offline and I should've kept that when I solve it. It took me 3~4h to solve and the half of the time I was looking for the cut from 196. Though optimization felt kinda nasty, 192 turned out to be pretty satisfying and the completion difficulty is there so overall this is a great level imo.
