I had the same problem, I made a 3x4 font that was just barely servicable for the initial project to show text on screen. It was my first (and only) font I ever made! Eventually I needed lower-case, so I turned those into lower-case and made a 3x5 variant for uppercase. It's still not ideal, and I'm sure when I announce my project, people will complain about it. So I've prepared to say "it's a stop-gap solution to make the OS servicable, but we can make more fonts."

I think people skimming a project often just don't quite get how much we pour into our projects, and how very much it cost us. But it's okay, they don't have to understand just how cool it is what we made. At least we know.

When I saw your video of your project, I was thinking to myself, "wow, that's incredibly cool, and I can relate to the steps he's doing!" Just trying to be the voice here of someone who thought that way, in case there are no others.
