But possibly it's a (or +21) for the whole thing. Let's test that on tht (if tht is cipher): t(20)-5=15→o, h(8)-5=3→c, t(20)-5=15→o → "oco" — no.

Take fydyw as first encoded word. If plaintext is there : t(20), h(8), e(5), r(18), e(5). Cipher: f(6), y(25), d(4), y(25), w(23). Differences: t→f = -14 or +12; h→y = +17; e→d = -1; r→y = +7; e→w = +18 — no. Download- fydyw tjss ly lhm mharm mn tht qb a...

Alternatively, "qb" could be "is" or "in". If q→i: q(17) to i(9) is shift -8 or +18. b(2) to n(14) is +12 — no. But possibly it's a (or +21) for the whole thing

This looks like a cipher or encoded message. Let me break it down. If plaintext is there : t(20), h(8), e(5), r(18), e(5)

Another guess: The string after "Download-" might be If we apply ROT-5 (Caesar +5): f(+5)=k, y(+5)=d (wrap: 25+5=30-26=4→d), d→i, y→d, w→b → kdidb — no.
