Here is an example of an icon I put through the program, then through ms paint, pixia, and gale(All same results), hand drew it best as possible, and shows the real icon.

The first icon face is the one I put through my 1-Bit image converter
Second is the regular icon(That I drew for the pixel art challenges and collabriation).
Third is my best possible hand drawn 1-bit version of the icon
Fourth is the same result from 3 different graphics programs(MS paint, Gale, and Pixia).
That has to be proof, that this program works. And if you think those were editted, run the icon in the program yourself. I used the default shade level for it(You can pick the shade level at start). default is perfectly balanced, so black is 1/3, dithering is 1/3, and white is 1/3.
So I really hope this game helps you guys out, if not its fun just to screw around with it, or plug in your best of best pixel art, and see what they would look like in a 1-bit format.
