I want to shout out another puzzle that inspired this one. Knowing which one it is will likely give a hint on how to solve this one. If you don't mind possibly getting that hint, you can click here to see which puzzle it is. I also name the specific puzzle and creator in my completion message

Note:
I realized that the first digit had a different and easier method of deducing than I had planned. I have since created an updated version of this puzzle that removes that easier break-in. After the break-in, the puzzle is exactly the same.
I am leaving the original puzzle with the easier break in, but if you want to attempt the updated puzzle to figure out my intended break in, Click here.
Rules:
Regular sudoku rules:
Place the digits 1-9 in every row, column, and box
Positive and Negative Diagonal Lines:
Place the digits 1-9 on both the main positive and negative Diagonals (The thin red lines that go from r1c1 to r9c9 and r9c1 to r1c9). Digits can not repeat on their respective diagonals.
Region Sum Lines:
Box borders divide each blue line into segments with the same sum.
White Kropki Dots:
White dots placed between two cells indicate the digits in those cells are consecutive (no negative constraint
Killer Cages:
Digits in cages must sum to the number in the upper left corner of the cage. No guessing is required to determine the value of x (x can not be a negative number as that would require the ability to insert negative digits, which you can not)
Note:
Some of the killer cage numbers are difficult to read, so below is a key you can reference that shows the killer cages number as well as the row and column numbers:
| Row | Column | Value |
|---|---|---|
| 1 | 5 | x+3 |
| 1 | 6 | 5x |
| 4 | 1 | 3x |
| 5 | 1 | x²-3 |
| 5 | 5 | x |
| 5 | 8 | 2x-1 |
| 6 | 7 | x²+6 |
| 7 | 4 | x+5 |
| 7 | 5 | x²+x |
Solution code: Column 1, read top to bottom

Added a link to an updated version of the puzzle. The original was designed with a difficult break-in. I realized an easier break-in was possible. I updated the puzzle to force my break-in
