Given the time, the most plausible quick manual solve: Try shifting (ROT-1):
Let’s try shifting forward: n→o, w→x, t→u, t→u → “oxuu” (no) nwtt aghnyt amy namt bkyr
n→m, w→v, t→s, t→s → “mvss” no Given the time, the most plausible quick manual
Test “nwtt” as “what”: w→n (shift -9?) h→w (+15?) no pattern consistent. Given the time
