Twb Wwyl - H-ntyng

Atbash: A=1→26=Z, B=2→25=Y, etc. Formula: new_position = 27 - old_position

"gjo jjly uaglat" — still not English. twb wwyl h-ntyng

So "twb" →

Given the pattern, this is likely an that reads something like "good day to you" if spaced differently. But "twb" = gdy, not good. Atbash: A=1→26=Z, B=2→25=Y, etc

— which is nonsense unless it’s an anagram or another layer. twb wwyl h-ntyng
