This is my first puzzle submission, and I'm very excited to see how folks do!

Sudoku rules apply.

Draw a single closed loop that travels orthogonally through the centers of some cells. The loop does not use any cell more than once and must travel through each colored square in the following way:

• The loop must turn 90 degrees upon reaching the purple squares, and may not turn on the blue squares.
• The value in each colored cell is the sum of the number of squares seen by the the 2 straight lines going out of that square, including itself. (This loop loosely follows the rules of the pencil game Shingoki.)
• Non-purple and non-blue adjacent digits on the loop must differ by at least 5. The loop acts as 17 German whisper lines excluding the blue and purple squares.
• Cells joined by an X sum to 10. Not all X's are given.
