I made this one so much harder than it needed to be. Realized at the end I missed something super easy. Took me 28:29. Really fun one.

Very interesting puzzle, enjoyed it quite a bit.
I think that the better way of formulating the skyscraper rule is to say the clue shows the number of skyscrapers it can see on the row/column. This removes the confusion by AshBrown.
