works with 0-9, use the switches in the top left and left, (the empty space in the top left is a switch, it just got bugged), uses binary, from top to bottom the switches are 1, 2, 4, and 8 Hold space to see the wires
SUPER laggy so will take a while to activate a switch and also takes a while for it to fully update, fortunately you can still switch before its done updating the display don't try numbers above 9, they don't work because I couldn't fit them all in the grid if I was messing around and broke something, or if the grid isn't completely filled, press L to fix and then press the flag
