Foggy Skyline 2, by Henry

Normal Sudoku rules apply: you must place the digits 1 to 9 in each row, column, and 3x3 box without repetition.

The grid represents a city covered in fog, where buildings of different heights rise into the sky. Each digit represents a building and its height. When you place the correct digit, the fog clears, revealing all other buildings in the same row or column that are shorter. However, taller buildings block the view, so only the shorter buildings up to the next taller one are revealed.

Some of the buildings rooftops are connected by stairs or ladders.
Stairs are marked with a white dot and the connected digits must be consecutive.
Ladders are marked with a black dot and one of the connected digits must be double the other.
Note: Not all possible dots are given.

Can you bring clarity to this foggy city?

If you find yourself lost in the fog, remember: you may need to remove a digit to uncover the true solution.
No guessing is required.

Good luck, and enjoy exploring the foggy city!

This is my second attempt with these rules and I believe the solution path turned out much more elegant this time. :)
