Ttbyq Msaryf Mhkr -

t (20) → g (7) t → g b (2) → o (15) y (25) → l (12) q (17) → d (4) So "ttbyq" →

This looks like a simple cipher, likely a (shift cipher) where each letter is shifted by a fixed number. ttbyq msaryf mhkr

I notice "mhkr" — if ROT13 → not obvious. t (20) → g (7) t → g

Hmm, maybe , then ROT13?

Try QWERTY up one row (e.g., w→2, e→3, but letters to letters? Not consistent). y (25) → l

Reverse "ttbyq" → "qy btt" → apply ROT13: q (17) → d, y (25) → l, space stays, b (2) → o, t (20) → g, t (20) → g → ? No.
