I'm interested in putting this in my project. Could you make a version with cleaner wiring and spaced out components?

If you download it from the itch.io app then it lets you download

All of my circuits for the negative sign.

You’ll need to use a second 7-segment display for that. The solution for it that I came up with is a little convoluted but I can send you some pictures

The 7-segment display colors as it stands now use the same color as the red and the blue wires when active (i think). I think it'd be pretty neat if the color pin could detect the color of the wire coming in and take its color.
