    That was a workout for me. Somehow i failed to see a logical step on the right side for an unbelievably long time, but it was very rewarding to find it eventually! Also, this puzzle fully justifies the use of thermo shapes vs signs, which could be used in a normal thermo sudoku, but not in this variant. Very nice puzzle with so few givens!

    11:59 .I had the exact same difficulty having failed to spot a fairly straight-forward deduction which could help fill the thermo on the right top.This made the difference from a GM time.

    A really cool and fun sudoku!
