06:08. Did I just see a rather large trick involving R3C6 and R7C7? Not sure whether that one had too much guesswork (I feel like I did a lot), but this is a pretty impressive (in terms of difficulty) puzzle. Nicely done!
I don’t think you really need guesswork: at some parts you can realize that sometimes two black squares cannot be two apart in a row, so they must be four apart in that row.
I think the main trick in the middle of the solve is to figure out how you can orient the 2 down, so that you don’t lead an odd number of ends into the left top of the grid.
2:48. Very neat. I don’t recall doing much with the R7C7, though the R3C6 was a sticking point.
