I was clearly missing something relatively simple as i found this more like 3 / 4 *!

Thank you for your comment, Lovejoy! The solve does not require advanced techniques, but at some points the scanning is somewhat challenging. As I have stated in the introduction, I would estimate this puzzle closer to 2/5, but as a setter I always struggle to properly determine the difficulty of my own puzzles.
Kind regard, sujoyku
