Dragging wires is a bit annoying sometimes they don't drag across T-T and the game concept is very interesting. Do the wires have to complete the circuit to change the frequency? It seems like they don't have to but the game says it's the correct number and doesn't let me progress. Quite odd.
I tried to improve dragging wires issue before but failed due to my beginner coding skill TT
And about the frequency, it changes regardless the wires complete connection, but both conditions need to be met to pass the level. My assumption is you might missed pressing the red button or there're some technical issues. Can you tell me which level you found this problem?
Sorry for late reply and thank you for your feedback kub!
