Couldn’t figure out how to solve this one without bifurcation, but still a nice puzzle. Felt like it was missing a clue to make it a true 1-star puzzle.
AaronH: Thanks for the feedback. There's a short logical line - no branching needed, but it’s definitely not the most obvious step. I’ve got a video up if you want to see how I was expecting it to go - link on puzzle page. Cheers :)
