Rules:
Fill some cells with water. If a cell is filled with water, all other cells within the same region that are in the same or a lower row have to be filled with water as well. Clues outside the grid indicate the number of water cells in the corresponding row or column.
Solution code: column 2 from top to bottom, W for water cell and X for empty cell (e.g. WXWXWXWWW)

Really interesting puzzle! Seemed straight forward and then id get stuck in a loop of possibilities, thinking one move was inevitable only to find out it wasn't. Still finished fairl quick and thoroughly enjoyed it the whole time :D

Really enjoyed! Logic flowed very smoothly after I understood the ramifications of the rules better.
Here’s the solution link on SudokuPad if anyone wants it (1 for water tile, 0 for empty): https://sudokupad.app/646ecpt6q0

I didn’t like doing this in Sudokupad, so I made a copy of it in Penpa+ (sorry for the unshortened link)
