This font was inspired by titles I saw on a show about espionage. I made mine with an even thinner stroke weight. So thin, in fact, that it barely even shows up on the screen at small point sizes. If you aren't anti-aliasing (using font smoothing) this font will give you real trouble unless you use a huge point size.
I made Secret Code with all caps in mind but I included lower case letters and a full ASCII character set just in case I wanted them later.
