Commander Keen is a series of side-scrolling video games released by id Software between 1990 and 2001. The games Follow the adventures of an eight-year-old genius, Billy Blaze, and his defense of Earth against alien threats.
As a game series involving aliens and space travel, naturally, it needed an alien-looking writing system. The galactic alphabet called the galactic alphabet, which appeared in numerous puzzles over the years and was the key to acting out secret areas in the game
Years later in the indie-hit game Minecraft The Galactic Alphabet makes a reappearance as a very subtle Easter egg homage. Modern Minecraft players (many of them the age of Billy Blaze, boy genius) may not recognize the symbols that float around the game's enchanting table or appear on the table's menu when creating enchanted items, but the floating and written glyphs are none other than the letters of the galactic alphabet from Commander Keen —as seen in the screenshot here.
Alas, even though the Galactic Alphabet is a one-to-one substitution for the Latin alphabet, you won't have much luck translating into the Minecraft enchanting table into actual in-game enchantments like Looting, Thorns, or Unbreaking. The enchanting table's output is random and the glyphs found are random too. What you see on the pages of the book when you attempt to convert amounts to gibberish created from a list of a few boxes randomly arranged.
