Thanks so much!
I'm thinking of buying the game, but Itch.io doesn't accept steam money :C
also have you though of different-bit inputs? I remember there was a level where you had to compare 2 4bit inputs with a 1bit input.
I thought I had to split the wires to add them together. for example, an and gate has 1 imput require 4 bit and the other 1 bit, so it compares the 1 bit with the other bits. as if the 1 bit wire was 4 bits of 1's or 0's.
