密碼破解簡易指南

I was stuck on a puzzle in Cosykiller for days until I grabbed this guide—the compact layout makes it easy to flip between sections mid-game, and the substitution alphabets are laid out way clearer than anything I found online. Perfect little sleuthing companion.

The section on common letter substitution alphabets is laid out so clearly that I cracked my first puzzle within an hour of reading it. It's compact enough to keep next to my keyboard during Cosykiller sessions.

Finally got my hands on this guide after struggling with some of the later puzzle ciphers in Cosykiller. The compact layout makes it easy to flip through mid-game without breaking immersion.
