{ZDNCUJTQU KSSF! (code2)}
It's hard, I do everything.. Caesar cipher (shift26), i read (code/hint) vertically, I looked at the code in the mirror+/upside down - → ↑ ↓ ←,exclude this characters from English alphabet, find words with 9 letters, and 4 letters...etc.
........
~I think S= O/E, and maybe U=E, so S=O.. =| ????e???e ?oo? |~#
〜 It's took maybe 4 hours . 〜 *sigh*
...we need another hint c: (looks like it's over to get hint (last login last year))... I have some questions▿ ..
question1: How "tengaku squared" know (YKOTFRL) is "friends"? maybe it might be another word.
question2: "Hint: Every time you use DCW, you see this" see what?
-In fact it was fun...
