Thanks so much!
I'm sure it's no surprise that I didn't have time to implement everything planned, and I did intend more instruction. I really like your idea of using a Caesar Cipher.
I did as much of the Ascii art completely by hand as possible, but I will admit some of the images in the intro and outro were made using public domain images as a basic template to draw off of (not that it was exactly trivial getting the desired look, especially in the time I had left).
