well, I had to delete a digit and place it back to see the completion message again since I usually do not look at it really and just close it right away.
aaanyways, really nice puzzle.
The break in was really hard for me, but after that initial wall... smooth sailing right to the end.
Very satisfying and fun

Some people use pencil and paper to solve. A top row solution code would be nice.
