Given the failure, perhaps it’s (AZERTY)? If so, “thmyl” on AZERTY shifted could be “the my”? But AZERTY: t and h are same positions, m is different. 9. Another possibility: thmyl = “ the my ” but with ‘y’ and ‘l’ swapped? Or maybe it’s an anagram ? “thmyl” anagram: “my thl” — no.
Let’s instead assume to get plaintext. That means: cipher letter = plain letter’s right neighbor. So to decode, shift each cipher letter left on keyboard. thmyl lbt twisted metal 2 llkmbywtr mn mydya fayr
This string — "thmyl lbt twisted metal 2 llkmbywtr mn mydya fayr" — appears to be a form of (often called “keyboard walk” or “nearby keys” substitution), possibly combined with a simple transposition or phonetic mangling. Given the failure, perhaps it’s (AZERTY)
Try thmyl → “”? t→t (no), h→h, m→i? No. “thmyl” anagram: “my thl” — no
