Not easy to break in by any margin, but once the break in happens, it gets going so smoothly! Love it

Tough puzzle, but satisfying. Caught on to the concept needed for break-in fairly quickly, but needed some trickier steps to progress mid-solve. Very nice!

Hi Aeon. A small suggestion for you. For the colour-blind-friendly version of the puzzle, I would either use thin white lines over the purple lines and call them ‘hollow’ or make one of the line types thinner. I’m not colour-blind myself but it was hard to tell the lines apart.
Thank you for the suggestion. I'm on it!
