I mean, it IS a square, after all

Thanks to Razalynn, Davide, and MrMeme for testing. Suggested rating was 2/5, but one tester found it 4/5. Seems some people found this puzzle easy and others quite difficult.
Regular sudoku rules apply. Except that the value of every digit is squared. (A six has a value of 6*6=36)
German whisper lines: values on a green line must differ by a value of at least 5 squared (or 25).
Region sum lines (rsl): values on a blue line must sum to the same value when divided by region borders.
Hint 1: You can work out the 4-1 rsl line right away, but it may be faster to wait until you've narrowed it down a bit.
Hint 2: Remember the pythagorean theorem: a^2 + b^2 = c^2. Where could it fit?
Hint 3: You may need to work out all the 2 cell sum combos. How many possible pairs sum to the same number?
The puzzle:

Fun puzzle! Was initially challenging in figuring out the combos that worked on the RSLs, but was very smooth and satisfying afterwards!

I have this at 2 stars. I only found it hard in that a large part of what we know about both regions sums and GW lines has to be tossed out, but once you wrap your head around it, theres not that many combinations of numbers that work on most of these lines. I found this to be very clever and fun!

Thank you for playing, I hope you enjoyed it!
