Moongloss was created to be a display font. A font that you would use to display the date, time, or little bits of information. There are many fonts out there that are meant for things for this, but none quite like this font.
So what is Moongloss? It's meant to fulfil the following design criteria:
1. To look reasonably futuristic, like it would feel at home in a sci-fi movie
2. To look polished and elegant. There are fonts that meet criteria, but fail at this regard
3. To be as monospaced as possible but still look good. Let's say you made a clock display with this font. A thin number '1' vs a fat number '8' will mess up the aesthetics of your display when minutes change and cause your entire clock to shift to the left or right. As such, numbers are strictly monospaced and are the same size in this font, but letters are variably sized to maintain an even appearance.
