...So I made one myself. It's called SGA Vorticon Monospace. Download here.
Besides the font itself, the ZIP file contains a README and some other stuff. Users who wish to simply use the font (i.e. probably everybody) are encouraged to ignore and/or discard these things. Especially the README, which contains more documentation than any font should ever have.
Oh, and happy 3/14.
Update, 3/21:
I added digits. Because SGA doesn't seem to have any of its own, I made up some new digits that are kind of sort of based on the English text in episode three. It's still in the same spot. If you downloaded the earlier version, you may need to:
- Clear your browser cache. If the old version is still in your cache, you might end up re-saving the old version when you go to download the new one.
- (Windows) Manually uninstall the old version. In particular, loading the new version with the Windows Font Viewer will continue to show the old version while it's still installed.
- (Unix-like systems only) Clear your fontconfig cache, otherwise the new digits may not show up, or they may only show up at certain sizes, or other fun things may happen.
