Rules
Normal Sudoku Rules Apply: Place the digits 1-9 in every row, column, and 3x3 region.
Eraser Cells: There is one eraser cell in every row, column, and box. There are no duplicate digits in the eraser cells. The value of an eraser cell is always 0. The value of non-eraser cells is the digit in the cell.
Thermometers: Values along a thermometer increase from bulb to tip.
V Clues: Cell values separated by a V sum to 5.
Killer Cages: The cell values in a cage must add up to the small total given in the top-left corner of the cage. There are no duplicate values in a cage, however there may be duplicate digits in a cage.
German Whispers: Neighbouring/adjacent values along a green line have a difference of at least 5.
Dynamic Fog: The grid is covered in fog. Entering correct digits will clear the fog. No guessing is required.
Difficulty: I’d rate this puzzle around a 3.5 in difficulty. I’m starting with an average rating and may adjust it based on feedback. I’m not the best at judging the difficulty of my own puzzles.

Updated Puzzle. thanks to Zibl for finding an issue. The sudoku link has now changed to the fixed puzzle: https://sudokupad.app/r8q2vxllgt
Minor change in the puzzle: clears fog slightly earlier to disambiguate an early step in the puzzle.
