Rules
Normal sudoku rules apply.
Along green lines, adjacent digits differ by at least 5.
There are six snakes in the grid, each consisting of a line moving either orthogonally or diagonally through centers of cells. No cell may be visited more than once - neither by the same snake nor by different snakes - but two snakes may cross each other at a cell corner.
The endpoints of each snake are given as a pair of color-matched circles.
Additionally, snakes act as thermometers: digits along a snake increase from one end to the other.
Three of the six snakes have equal sum of digits (including both ends).
Solution code: Row 3

Congratulations! What a hard and intresting puzzle!
How is it even possible to come up with something this out of the box? I'm impressed!

ND: Thanks for the comment!
Restricting the snakes' paths is quite tricky indeed.
