Rules:
Sudoku: Place the digits 1-6 exactly once in each row, column and box.
X-Sums: Fill each circle with the sum of the first X digits from the direction of the circle, where X is the digit in the cell next to the circle. These sums may be one- or two-digit numbers.
No digit may appear more than once in circles (e.g. having both "12" and "20" in circles is not allowed; having "11" in a circle is not allowed.)
Solution code: row 2

Incredible how this even worked out at the end, let alone being entirely logical to work on. Thanks both for this beautiful smol puzzle x)
