What a beautiful puzzle. I'm not really a big RSL puzzle person; never really felt comfortable with their logic, but I decide to challenge myself on this one and I am SO glad I did.
Definitely the most challenging RSL-only puzzle I've ever completed, but well worth it. A true gem.

Great puzzle. I missed the communication between the top and the bottom for hours before solving.
