Dear visitor, be warned:
If you enter this castle of 99 Chambers, you may be locked in forever.
But do as you wish. If you decide to enter, remeber to use small-case letters and numbers
in order to unlock the doors. Be sure to pack Google, Purplehell, some useful software,
and don't forget your brain outside - you will need it. Good luck!
