The download link they use is axfc.net and they put keyword
When i search this password's game( I use google translate),I saw the author write something For the hint of the keyword file..'' As for the password, we ask you to be familiar four letters beginning with t (it is not "tori"). "
Tori mean bird, but the keyword begin with "t" four letter. I already know but I will give this simple hint. " Its about clock " Good to figured it out! Sorry my bad english:)
