Back to old times eh? I apologise firstly for the delay in getting a puzzle out in the first place, and secondly for then putting out something broken.
No such issues with this one. It’s moderately monstrous. I guess what with the small size and everything, some of the intended logic might get lost in small bifurcation chains, but I want you to know, dearest reader, there is definitely an intended solution path and I am really quite pleased with it.
