Interestingly never met a 2-off. Was just stuck 4-off until I realized there was more than met the eye in one area, and then the solve was instant. Very sneaky.
Very cool level. Steady progression from 4-off to multiple 2-offs to the solution. Really love the way the final path ends up mixing some of the portions of the level together. Very satisfying to work out.
I liked it but for me that's one more case where I can't identify the difference between the winning route and those I tried before. That's a bit frustrating.
