Seriously clever puzzle, I agree it's closer to 4 stars than 3. But there is reward for effort - after a lot of colouring and finally disambiguating two key digits (after about 90 mins) the finish was very quick.

Thank you for your comments, @zardoz37, @fractalminding, @vitaminz and @Black_Doom! I am glad that you enjoyed the puzzle.
Considering the difficulty: I also believed it to be a little harder, but testing feedback consistently had it at 3*.
Kind regards, sujoyku

Good lord I found it ridiculously hard to find the logic required to solve this!

Another great one! Once I knew what to look for, and when, it flowed quite nicely.

Super fun Killer. Love the theme too, fun solve from the break-in right till the end.

Not easy. At least 28 has more limited options for 4 cells. This was very good, spotting how the smallest things can sharply limit the placement of digits. Great puzzle and enjoyable hour!
