I think I was fortunate that *********************************************************************** so I never chanced upon the unfortunate 2-off. :) Cute puzzle.
That solution is pretty exceptional. Took me ages to finally be able to see it as an option.
Edit: I just beat this level again now, 11 months later. It didn’t take me nearly as long as the first time, and I didn’t find the solution quite as exceptional as I did originally. Maybe that means I’ve matured as a Pathology player? :) Either way, still a very clever solution, and feels very logical. Good level.
