Enhanced maintenance and security

Yesterday, we maintained and strengthened the security of various "CGI games."

Specifically, we made it impossible to refer to data files and log files that were partially visible.
In addition, there was a mail address that was written, so we made it possible to hide it.

Also, because there were some defects, we are also fixing the defects.
(Currently, I think that it can be used without problems.)

Thank you for your continued support.
