Click the buttons (top for reverse, bottom for normal) Red is S1 Episodes 1-7 while black is all the rest of S1. Yellow is the Weirdmaggedon theme. The Whispers tell you how to decode the ciphers at the end of each episode! For example: KHOOR is HELLO using the Three Letters Back method hinted in Red! While HELLO in Black is SVOOK! That method is the Switch A and Z cipher! In Weirdmaggedon it says I'm watching you
