I don't even know how to input the code if I did get it. Maybe it is something with the type of computer I have? when I say the puzzle has no feedback, I meant that the only thing that I seem to be able to do is select the different blocks and digits of the display, and to press the button, which flashes and makes a beep. when I say this puzzle has no feedback, I mean that it doesn't seem like there is any other visible state for the puzzle to be in other than the win state.
How do I even input the code?
After looking at the related collection of puzzles, I understand that this last part of my comment is irrelevant, but the question remains, how do I input the code? it says the answer is in letters, so can you tell me how to covert letters into button presses?
