Tangled Trajectory

• Normal sudoku rules apply.
• Arrows: The digits along each arrow must sum to the digit in the circled cell. Digits may repeat on arrows if allowed by other rules.
• Quasi-Global Alternative Entropy: Every 2x2 of cells in the grid that contains a cell on an arrow (circles included) must contain a digit from each of the following sets: {1,2}, {3,4}, {6,7}, and {8,9}. The digit 5 is "wild" and can be used in the place of one other digit in each of these 2x2 of cells.
