Looking at your comment again I totally blanked on replacing the title 'Puzzle' with the actual name of the puzzle, loool. Thanks for catching that, totally slipped my mind.
I agree with many of your points. The 'solved 01/' is some weird quirk of the font I used (I think) that I can't quite figure out, it's supposed to read 'solved 0/1', referring to each receiver on the board. I also like the idea of using number keys for the different gears. Regardless, thanks again for your feedback.
