Tighter NOT circuits.

Finally (?) done patching up levels so that the outputs cannot be predetermined before following the flow of input signals and logic gates.

Update

Minor change to "Routing" to avoid early solution to final island.

Simple "crossing" setup found. Happy to leave campaign as-is at this point.

The previous 'crossing' setup was actually incorrect for all cases. This level has been dropped in favor of additional gates. Further, the maps did not make it clear which signals were starting/input signals vs ending/output signals. Fixed this in the latest version. Additionally, all gates have been shrunk down to show all possible inputs. New gates include OR and XOR. Crossings can be achieved with three splits and three XOR gates. Working on additional levels to show this.
