#35 "Aurora" - Little Killer & Palindrome X Sudoku

This puzzle was made for Tom1i as part of the CTC Secret Santa 2020 event! I was pushed well out of my comfort zone with this puzzle but I think it came out nicely Each row, column, 3x3 box and marked diagonal must contain the digits 1 through 9

Clues outside the grid give the sum of the digits along the indicated diagonal, and may include repeats

Grey lines each form a palindrome, in which the digits placed along the line can be read the same forwards as backwards Solve on F-Puzzles https://f-puzzles.com/?id=y64oc76v
