This time a path construction puzzle which should be still quite approachable. This was quite the effort to create, but I think this could be another ruleset with potential. Have fun!

Normal Sudoku rules apply.

Green laser: Adjacent digits on a green line must differ by at least 5.

Red laser: Draw a straight red laser beam starting at r1c2 and ending at the red dot in r1c7. Adjacent digits on the beam share the same parity (odd or even). Each time the beam crosses a box border, this parity switches. The beam may cross itself but may not reverse direction.

Prism: When the red laser beam hits a prism, it continues in one of the seven possible directions (four orthogonal or four diagonal, excluding the direction it came from). The digit in a prism indicates the number of cells the beam travels before hitting the next prism (or the final red dot). The red laser beam visits each prism exactly once.

Fog: Some green laser beams are hidden by fog. All prisms are visible!

The laser pointer handles (e.g. r1c1) are not part of the beam and only there for aesthetic reasons.

Hints for the break-in:

There is no need to start the construction at the beginning. Each prism needs a destination where it is pointing to (which is either another prism or the final red dot). This limits the possible digits for each prism. Combine this with the parity constraint and eventually you have your break in.

There are multiple break-ins for sure, but the prisms in box 6 are quite limited...
