Happy Birthday to Bremster from the Sudoku Skunkworks.
Rules
Normal Sudoku and Killer cage rules apply.
Digits in cages must sum to the number given in the top left corner. Digits may not repeat in cages.
Black cages are regular killer cages.
Red cages are both psycho killer cages AND regular killer cages.
In psycho killer cages, the digits in the cage point to boxes in the grid, and provide a referred cell which is in
the same position in both boxes. The digits referenced by the cage must also sum to the small clue in the top
left corner of the cage.
For example, if r1c9 were an 8 and r2c9 were a 6 (making a valid 14 killer cage), the referred cells in boxes 8
and 6 (r7c6 and r5c9 respectively) must also sum to 14.

Lovely modification to killer! I appreciate how approachable the added killer+psycho killer combination makes the whole psycho killer constraint.
