Primes are too cool to be constrained

- Normal Sudoku rules apply.
- Normal Arrow rules apply. Digits along an arrow must sum to the number in the corresponding circle.
- Normal Palindrome rules apply. Numbers along a palindrome read the same forwards and backwards.
- Normal Kropki rules apply. Cells seperated by a black dot have a 1:2 ratio. Not all black dots are given.
- Normal Fortress rules apply. Cells indicated with 4 outgoing arrows are larger than all of their orthogonal neighbors.
- No prime number can be orthogonally adjacent to another prime number.
If you are not familiar with prime numbers, prime numbers are defined as numbers who are only fully divisible by themselves and the number 1. In this puzzle's context (as the initial look of the puzzle may suggest), the prime numbers are 2, 3, 5 and 7.

Very very very nice puzzle ! My first 3 stars solve, spent 2 hours on it and it was totally worth it. Thank you for such a nice time, loved the prime constraint.

Very nicely themed and elegant, not too hard if you're good at scanning (which I'm sadly not)

Beautiful Puzzle! However I also think its more of a 3 Star, but its tough to judge for me. Thanks for the Puzzle anyway!

I really liked it! For me it was more of a 3 stars, but I might be wrong.
Thanks!
