Rules
Normal sudoku rules apply.
Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area may be completely shaded or unshaded.
The value of a shaded cell is equal to the negative of its digit, and the value of an unshaded cell is equal to its digit.
Within a cage, values sum to the small number in the top left corner.
Lösungscode: Shaded digits in row 5

Wow, this one was quite tough, but a LOT of fun. Got stuck near the middle for awhile until JUST the right question popped up, then a whole bunch of stuff started to fall into place and it was relatively smooth from there.
Great puzzle, thank you for setting!

I found this tough going but really fun. Once I realised the trick to it it went a lot smoother though. Awesome puzzle.

There are some very elegant interactions between the two constraints. Thanks for sharing.
