Should’ve edited to say,
only recommended to solve this one if you like to solve brutal puzzles.
Not sure if the testing channel on discord is going to help, so blindly posting it here in hopes it is still enjoyable. I don't think this one is as challenging as Sayori II.
Rules:
-Normal sudoku rules apply.
-Digits cannot repeat along the marked diagonal.
-Digits along a thermo must increase from the bulb end.
-The blue lines are region-sum lines, where each segment of a line passing through boxes must have the same sum.
